Technical Interview Questions and Answers

1. Explain the difference between Stack and Heap memory.

Feature	Stack Memory	Heap Memory
Usage	Local variables, function calls	Dynamic memory allocation
Size	Small, fixed size	Large, grows dynamically
Speed	Faster access	Slower access
Management	Automatic (compiler managed)	Manual (programmer managed)
Lifetime	Limited to function scope	Until explicitly freed
Fragmentation	No fragmentation	Can get fragmented

Example:

void function() {
    int x = 10;           // Stack
    int[] arr = new int[10];  // Array reference on stack, object on heap
}

2. Write a program to find the first recurring character in a string.

def first_recurring(s):
    seen = set()
    for char in s:
        if char in seen:
            return char
        seen.add(char)
    return None

# Test
print(first_recurring("hello"))      # 'l'
print(first_recurring("abcdef"))     # None

Time Complexity: O(n) Space Complexity: O(k) where k is character set size

3. What is the difference between Truncate and Delete in SQL?

Feature	DELETE	TRUNCATE
Type	DML command	DDL command
WHERE clause	Can use WHERE	Cannot use WHERE
Speed	Slower (logs each row)	Faster (logs deallocation)
Rollback	Can be rolled back	Cannot be rolled back (usually)
Identity reset	Does not reset	Resets identity to seed
Triggers	Fires triggers	Does not fire triggers
Space	Space not reclaimed immediately	Space reclaimed immediately

4. Explain Design Patterns (Singleton, Factory).

Singleton Pattern: Ensures only one instance of a class exists.

public class Singleton {
    private static Singleton instance;
    
    private Singleton() {}
    
    public static synchronized Singleton getInstance() {
        if (instance == null) {
            instance = new Singleton();
        }
        return instance;
    }
}

Factory Pattern: Creates objects without specifying exact class.

interface Shape { void draw(); }

class ShapeFactory {
    Shape getShape(String type) {
        if (type.equals("circle")) return new Circle();
        if (type.equals("square")) return new Square();
        return null;
    }
}

5. Write a program to implement LRU Cache.

from collections import OrderedDict

class LRUCache:
    def __init__(self, capacity):
        self.capacity = capacity
        self.cache = OrderedDict()
    
    def get(self, key):
        if key not in self.cache:
            return -1
        # Move to end (most recently used)
        self.cache.move_to_end(key)
        return self.cache[key]
    
    def put(self, key, value):
        if key in self.cache:
            self.cache.move_to_end(key)
        self.cache[key] = value
        if len(self.cache) > self.capacity:
            # Remove first item (least recently used)
            self.cache.popitem(last=False)

# Test
cache = LRUCache(2)
cache.put(1, 1)
cache.put(2, 2)
print(cache.get(1))    # 1
cache.put(3, 3)        # Evicts key 2
print(cache.get(2))    # -1

6. What is the difference between Shallow Copy and Deep Copy?

Shallow Copy: Creates new object but references same nested objects.

import copy
list1 = [[1, 2], [3, 4]]
list2 = copy.copy(list1)  # Shallow copy
list1[0][0] = 999
print(list2[0][0])  # 999 (affected!)

Deep Copy: Creates new object and recursively copies nested objects.

list1 = [[1, 2], [3, 4]]
list2 = copy.deepcopy(list1)  # Deep copy
list1[0][0] = 999
print(list2[0][0])  # 1 (not affected)

7. Write a SQL query to find the second highest salary.

-- Method 1: Using LIMIT/OFFSET
SELECT DISTINCT salary 
FROM Employee 
ORDER BY salary DESC 
LIMIT 1 OFFSET 1;

-- Method 2: Using subquery
SELECT MAX(salary) 
FROM Employee 
WHERE salary < (SELECT MAX(salary) FROM Employee);

-- Method 3: Using DENSE_RANK
SELECT salary
FROM (
    SELECT salary, DENSE_RANK() OVER (ORDER BY salary DESC) as rank
    FROM Employee
) ranked
WHERE rank = 2;

8. Explain the difference between Synchronous and Asynchronous programming.

Feature	Synchronous	Asynchronous
Execution	Sequential, blocking	Non-blocking, concurrent
Waiting	Waits for task completion	Continues with other tasks
Complexity	Simpler	More complex
Use Case	Simple, short operations	I/O operations, network calls
Performance	May be slower for I/O	Better resource utilization

JavaScript Example:

// Synchronous
const result = fetchData();  // Blocks until complete
console.log(result);

// Asynchronous
fetchData().then(result => {  // Non-blocking
    console.log(result);
});
console.log("This runs first");

9. Write a program to check if a binary tree is balanced.

class TreeNode:
    def __init__(self, val=0, left=None, right=None):
        self.val = val
        self.left = left
        self.right = right

def is_balanced(root):
    def check_height(node):
        if not node:
            return 0
        
        left_height = check_height(node.left)
        if left_height == -1:
            return -1
        
        right_height = check_height(node.right)
        if right_height == -1:
            return -1
        
        if abs(left_height - right_height) > 1:
            return -1
        
        return max(left_height, right_height) + 1
    
    return check_height(root) != -1

10. What is Garbage Collection in Java?

Garbage Collection automatically reclaims memory used by objects that are no longer referenced.

How it works:

Mark: Identify objects that are reachable from roots
Sweep: Remove unreachable objects
Compact: Move remaining objects to reduce fragmentation

Types of Garbage Collectors:

Serial GC: Single thread, for small applications
Parallel GC: Multiple threads for young generation
CMS (Concurrent Mark Sweep): Low pause times
G1 (Garbage First): Default since Java 9, balances throughput and latency
ZGC/Shenandoah: Ultra-low latency collectors

Best Practices:

Set appropriate heap sizes (-Xms, -Xmx)
Minimize object creation
Avoid memory leaks (remove references when done)
Use try-with-resources for AutoCloseable objects
