TLE on CSES Graph Question LAb

Правка en1, от osource, 2020-10-22 20:21:46

Hello,

I was solving CSES problemset and am stuck in this question — Question My code — Code

I am getting TLE on 4 test cases. I'm not able to figure out why as I have used standard BFS and therefore the time complexity should be O(m*n). Can someone help me in this?
