Hey man, i solved ur memory problem with the following submission: https://mirror.codeforces.com/contest/1774/submission/186734301

However, I got a time limit exceeded on the next test (22). Do u think u could give me a time complexity analysis for ur code to see what is the problem?

    for my code the time complexity was O(n); where n is number of nodes

        The one thing more i have done is predefining the size of curr vector so to avoid mutliple times reallocation of size of the vector

Now i gets accepted by passing the visited vector by reference... !!

Thanks @TheOpChicken123 for pointing out.

Pass the reference for visted and curr vectors and make the necessary changes in update() and DFS() functions.

This is ACCEPTED submission of your code.

1st Change
2nd Change

Hope you got it right :)
