Your code gives WA as it does not stop on the path to one of the leaf nodes even after having greater than m consecutive vertices with cats,it refreshes the value of variable val to 0 on the same path and counts those leaf nodes as well.Example test case would be:

Input :

4 1

1 1 0 0

1 2

2 3

3 4

Output :

0 (but your code gives output as 1)

You can use a return statement to return from the path where greater than m consecutive vertices have cats.

you are right! thanks a lot.

Hey I couldn't understand why the answer is 2 in the second example shown in that problem.

The way I see it he can only go restaurant at vertex 5 through the path 1 -> 2 -> 5 which has only 1 cat. The path to 4, 6, 7 have 2 cats which exceeds the threshold.

Here is my code — https://pastebin.com/ws0frPRy

Thanks for your time !

The question asks for consecutive vertices so the path to 4 is fine since the vertices with cats are not next to each other on the path.

Thanks, I missed that part. Now it makes sense. I will try to update my logic.
