def lcs(text1, text2):
    m, n = len(text1), len(text2)
    dp = [[0] * (n + 1) for _ in range(m + 1)]
    for i in range(1, m + 1):
        for j in range(1, n + 1):
            if text1[i-1] == text2[j-1]:
                dp[i][j] = dp[i-1][j-1] + 1
            else:
                dp[i][j] = max(dp[i-1][j], dp[i][j-1])

            in_degree[v] += 1
    queue = [i for i in range(n) if in_degree[i] == 0]
    result = []
    while queue:
        u = queue.pop(0)
        result.append(u)
        for v in graph[u]:
            in_degree[v] -= 1

            dq.pop()
        dq.append(i)
        if dq[0] <= i - k:
            dq.popleft()
        if i >= k - 1:
