Question : “Problem - E1 - Codeforces”
My solution : “Submission #89107112 - Codeforces”
I simplify and write clean commented code, I think it will be helpful so I shared here.
Thanks, @galencolin ( after reading your code and dry run on paper, I finally understand where my previous code goes wrong )
@ssrivastava990, during contest i was not able even to approach the problem as i just know the basics of tree and graph, what else to know is required to solve this problem or this kind of similar problems?
practice all u need .
“Graphs Problems - Codeforces”
“Algorithm Gym :: Graph Algorithms - Codeforces”
It’s great actually
Thanks
