Technical Interview Questions and Answers

1. Explain the difference between Stack and Queue.

Feature	Stack	Queue
Principle	LIFO (Last In First Out)	FIFO (First In First Out)
Operations	Push (add), Pop (remove)	Enqueue (add), Dequeue (remove)
Access	Top element only	Front and Rear elements
Analogy	Stack of plates	Line of people
Use Cases	Undo operations, recursion, expression evaluation	Print spooling, CPU scheduling, BFS traversal

Implementation in Java:

// Stack using Java Collections
import java.util.Stack;

Stack<Integer> stack = new Stack<>();
stack.push(10);  // Add to top
stack.push(20);
int top = stack.pop();   // Remove from top (20)
int peek = stack.peek(); // View top without removing (10)

// Queue using Java Collections
import java.util.LinkedList;
import java.util.Queue;

Queue<Integer> queue = new LinkedList<>();
queue.offer(10);  // Add to rear
queue.offer(20);
int front = queue.poll();  // Remove from front (10)
int peek = queue.peek();   // View front without removing (20)

Python Implementation:

# Stack (using list)
stack = []
stack.append(10)  # Push
stack.append(20)
top = stack[-1]   # Peek
item = stack.pop()  # Pop (returns 20)

# Queue (using collections.deque)
from collections import deque
queue = deque()
queue.append(10)  # Enqueue
queue.append(20)
front = queue[0]  # Peek
item = queue.popleft()  # Dequeue (returns 10)

---

2. Write a program to find the Fibonacci series up to n terms.

Python Solutions:

# Iterative approach (preferred)
def fibonacci_iterative(n):
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    
    fib = [0, 1]
    for i in range(2, n):
        fib.append(fib[i-1] + fib[i-2])
    return fib

# Recursive approach
def fibonacci_recursive(n):
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    
    fib = fibonacci_recursive(n - 1)
    fib.append(fib[-1] + fib[-2])
    return fib

# Generator approach (memory efficient)
def fibonacci_generator(n):
    a, b = 0, 1
    for _ in range(n):
        yield a
        a, b = b, a + b

# Test
print(fibonacci_iterative(10))
print(list(fibonacci_generator(10)))

Time Complexity:

• Iterative: O(n) time, O(n) space (or O(1) if only returning last number)
• Recursive: O(2^n) naive, O(n) with memoization

---

3. What is the difference between Overloading and Overriding?

Feature	Method Overloading	Method Overriding
Definition	Same method name, different parameters	Same method signature in parent and child class
Class	Same class	Parent-child relationship required
Parameters	Must be different	Must be same
Return Type	Can be different	Must be same or covariant
Binding	Compile-time (static)	Runtime (dynamic)
Access Modifier	Can be anything	Cannot reduce visibility
Polymorphism Type	Compile-time polymorphism	Runtime polymorphism

Overloading Example:

class Calculator {
    // Overloaded methods
    int add(int a, int b) {
        return a + b;
    }
    
    double add(double a, double b) {
        return a + b;
    }
    
    int add(int a, int b, int c) {
        return a + b + c;
    }
}

Overriding Example:

class Animal {
    void makeSound() {
        System.out.println("Animal makes sound");
    }
}

class Dog extends Animal {
    @Override
    void makeSound() {
        System.out.println("Dog barks");
    }
}

// Usage
Animal animal = new Dog();
animal.makeSound();  // Outputs: Dog barks (runtime polymorphism)

---

4. Write a SQL query to find the Nth highest salary.

Multiple Solutions:

Solution 1: Using LIMIT/OFFSET (MySQL, PostgreSQL)

-- 3rd highest salary
SELECT DISTINCT salary 
FROM Employee 
ORDER BY salary DESC 
LIMIT 1 OFFSET 2;

Solution 2: Using Subquery (Standard SQL)

-- Nth highest salary (replace N)
SELECT DISTINCT salary 
FROM Employee e1 
WHERE N-1 = (
    SELECT COUNT(DISTINCT salary) 
    FROM Employee e2 
    WHERE e2.salary > e1.salary
);

Solution 3: Using DENSE_RANK (Window Functions)

WITH RankedSalaries AS (
    SELECT salary, 
           DENSE_RANK() OVER (ORDER BY salary DESC) as rank
    FROM Employee
)
SELECT DISTINCT salary 
FROM RankedSalaries 
WHERE rank = N;

Solution 4: Using TOP (SQL Server)

-- 3rd highest salary
SELECT TOP 1 salary 
FROM (
    SELECT DISTINCT TOP 3 salary 
    FROM Employee 
    ORDER BY salary DESC
) AS Top3
ORDER BY salary ASC;

5. Explain the difference between TCP and UDP.

Feature	TCP (Transmission Control Protocol)	UDP (User Datagram Protocol)
Connection	Connection-oriented	Connectionless
Reliability	Reliable (guaranteed delivery)	Unreliable (best effort)
Ordering	Ordered delivery	No ordering guarantee
Speed	Slower (overhead for reliability)	Faster (minimal overhead)
Header Size	20-60 bytes	8 bytes
Error Checking	Extensive error checking	Basic error checking
Use Cases	Web browsing (HTTP), email (SMTP), file transfer (FTP)	Streaming, DNS, gaming, VoIP
Congestion Control	Yes	No
Flow Control	Yes	No

TCP Handshake:

Client          Server
  |   SYN        |
  | -----------> |
  |   SYN-ACK    |
  | <----------- |
  |   ACK        |
  | -----------> |
  |  Connected!  |

When to use TCP:

• Data integrity is critical
• Order of delivery matters
• File transfers, emails, web pages

When to use UDP:

• Speed is more important than reliability
• Real-time applications
• Broadcasting/multicasting
• DNS queries, video streaming

6. Write a program to detect a loop in a linked list.

Floyd's Cycle Detection Algorithm (Tortoise and Hare):

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

def detect_loop(head):
    """Returns True if loop exists, False otherwise"""
    if not head or not head.next:
        return False
    
    slow = head  # Tortoise
    fast = head  # Hare
    
    while fast and fast.next:
        slow = slow.next           # Move 1 step
        fast = fast.next.next      # Move 2 steps
        
        if slow == fast:           # Loop detected
            return True
    
    return False

def find_loop_start(head):
    """Finds the starting node of the loop"""
    if not detect_loop(head):
        return None
    
    # Find meeting point
    slow = fast = head
    while fast and fast.next:
        slow = slow.next
        fast = fast.next.next
        if slow == fast:
            break
    
    # Find loop start
    slow = head
    while slow != fast:
        slow = slow.next
        fast = fast.next
    
    return slow

# Time Complexity: O(n)
# Space Complexity: O(1)

Alternative using Hashing:

def detect_loop_hashing(head):
    visited = set()
    current = head
    
    while current:
        if current in visited:
            return True  # Loop found
        visited.add(current)
        current = current.next
    
    return False

# Time Complexity: O(n)
# Space Complexity: O(n)

7. What is the difference between Static and Dynamic Binding?

Feature	Static Binding (Early Binding)	Dynamic Binding (Late Binding)
Binding Time	Compile time	Runtime
Method Type	Private, static, final methods	Instance methods
Information	Type information is determined by declared type	Type information is determined by actual object
Performance	Faster (no runtime lookup)	Slightly slower (runtime lookup)
Example	Method overloading	Method overriding
Also Called	Early binding	Late binding

Example in Java:

class Parent {
    // Static method - static binding
    static void staticMethod() {
        System.out.println("Parent static method");
    }
    
    // Instance method - dynamic binding
    void instanceMethod() {
        System.out.println("Parent instance method");
    }
}

class Child extends Parent {
    static void staticMethod() {
        System.out.println("Child static method");
    }
    
    @Override
    void instanceMethod() {
        System.out.println("Child instance method");
    }
}

// Usage
Parent obj = new Child();
obj.staticMethod();     // Parent static method (static binding)
obj.instanceMethod();   // Child instance method (dynamic binding)

8. Write a program to implement Binary Search.

Python Implementation:

def binary_search(arr, target):
    """
    Returns index of target if found, -1 otherwise
    Array must be sorted
    """
    left, right = 0, len(arr) - 1
    
    while left <= right:
        mid = (left + right) // 2
        
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    
    return -1  # Not found

# Recursive version
def binary_search_recursive(arr, target, left=0, right=None):
    if right is None:
        right = len(arr) - 1
    
    if left > right:
        return -1
    
    mid = (left + right) // 2
    
    if arr[mid] == target:
        return mid
    elif arr[mid] < target:
        return binary_search_recursive(arr, target, mid + 1, right)
    else:
        return binary_search_recursive(arr, target, left, mid - 1)

# Test
arr = [1, 3, 5, 7, 9, 11, 13, 15]
print(binary_search(arr, 7))        # 3
print(binary_search(arr, 10))       # -1

Time Complexity: O(log n) Space Complexity: O(1) iterative, O(log n) recursive

Key Points:

• Array must be sorted
• Each iteration eliminates half of the remaining elements
• More efficient than linear search (O(n)) for large datasets

9. Explain the difference between String, StringBuilder, and StringBuffer.

Feature	String	StringBuilder	StringBuffer
Mutability	Immutable	Mutable	Mutable
Thread Safety	Thread-safe (immutable)	Not thread-safe	Thread-safe (synchronized)
Performance	Slow (creates new objects)	Fast	Slower than StringBuilder
Introduced	Java 1.0	Java 5	Java 1.0
Use Case	Constant strings	Single-threaded string manipulation	Multi-threaded string manipulation

Example:

// String - Immutable
String s = "Hello";
s = s + " World";  // Creates new object, original unchanged

// StringBuilder - Mutable, faster
StringBuilder sb = new StringBuilder("Hello");
sb.append(" World");  // Modifies same object
String result = sb.toString();

// StringBuffer - Thread-safe
StringBuffer sbf = new StringBuffer("Hello");
sbf.append(" World");  // Synchronized method

Performance Comparison:

// Inefficient - creates 1000 objects
String s = "";
for (int i = 0; i < 1000; i++) {
    s += i;  // Creates new String object each time
}

// Efficient - modifies single object
StringBuilder sb = new StringBuilder();
for (int i = 0; i < 1000; i++) {
    sb.append(i);  // Same object modified
}

Recommendation:

• Use String for constants or when immutability is needed
• Use StringBuilder for single-threaded string manipulation
• Use StringBuffer only when thread safety is required

---

10. Write a SQL query to find employees who have been with the company for more than 5 years.

Table Structure:

CREATE TABLE Employees (
    emp_id INT PRIMARY KEY,
    emp_name VARCHAR(100),
    hire_date DATE,
    department VARCHAR(50),
    salary DECIMAL(10,2)
);

Solutions:

Solution 1: Using DATEDIFF (SQL Server)

SELECT emp_id, emp_name, hire_date, department
FROM Employees
WHERE DATEDIFF(year, hire_date, GETDATE()) > 5;

Solution 2: Using DATE_SUB/CURDATE (MySQL)

SELECT emp_id, emp_name, hire_date, department
FROM Employees
WHERE hire_date <= DATE_SUB(CURDATE(), INTERVAL 5 YEAR);

Solution 3: Using INTERVAL (PostgreSQL)

SELECT emp_id, emp_name, hire_date, department
FROM Employees
WHERE hire_date <= CURRENT_DATE - INTERVAL '5 years';

Solution 4: Standard SQL (works across databases)

SELECT emp_id, emp_name, hire_date, department,
       FLOOR(DATEDIFF(CURRENT_DATE, hire_date) / 365.25) AS years_of_service
FROM Employees
WHERE hire_date <= CURRENT_DATE - INTERVAL '5' YEAR;

Additional Query: Calculate exact years of service

SELECT emp_id, emp_name, hire_date,
       TIMESTAMPDIFF(YEAR, hire_date, CURDATE()) AS years,
       TIMESTAMPDIFF(MONTH, hire_date, CURDATE()) % 12 AS months
FROM Employees
WHERE TIMESTAMPDIFF(YEAR, hire_date, CURDATE()) > 5;
