Can someone please help me in debugging this code
By sourabh_jangid, history, 5 years ago, In English

I was trying to solve this problem (56E - Domino Principle). I am stuck on Test Case 30.(Link to my submission 58845497). I tried for hours but not been able to find my mistake. My algorithm is same as the editorial given, but it is giving wrong answer verdict on test case 30. Please help me in debugging the code, and also share some debugging technique, what you use during a contest.

No, you should debug your programs yourself

      Write a brute force generator, and use the official solution as a checker. You should be able to find a small case that fails.

Why would someone waste his time debuging others' codes?

Just for fun, I tried something a little gimmicky. I looked for other submissions that got WA on test #30 (by using the status filters). Bubble_Master also got WA on test 30 (on the same output token, too) and then changed their solution slightly and got AC. Maybe you can compare their WA/AC submissions and get a hint about your mistake.
