Well ,I resolved the issue by myself. Actually, clearing all the adjacency vector and setting the mark/visited boolean array from one to 300005 in each iteration was causing TLE. I should have done it only upto given n. Got AC after setting it! Hope, it will help others.
Thanks for sharing your experience. Note that the C++ class constructors/destructors and dynamic-memory management functions can do the mark/visited and adjacency vector initialization and clearing automatically if these objects are declared locally inside the solve() function. Check the following code for an example.
