I’ve also tried the int long to long long , long unsigned…but getting the same error.

thanks…

The size of your array is n so the highest index you can access is n-1 but you are accessing index n as well so declare a bigger array.

I’ve increased the array size and optimize the code …But…

still getting W.A.

cud u suggest me the test cases where the code is failing…thanks!!

seems like you are using a matrix to represent the graph which won’t work because n <= 10^5. Your approach seems wrong too. Have you read the Editorial ? If not read it and any data structure or algorithm you don’t understand learn it from here : Data Structures and Algorithms - tutorial - CodeChef Discuss

@topcoder_7 Atleast explain where he’s going wrong or give some hint. Directly giving him the solution is not going to help him.

If he compares the solution he’ll know. I’ve include the part which he has to remove from his code in comment region(/***/)
