Doubt in MIKE3

I just want to know why my this submission didn’t worked but a recursive brute force worked. Can you give me a case where it fails.
Thank you :slight_smile:

I updated the link. Sorry for the confusion.

I got that but I never got the case where it fails. Finally I wrote up the recursive brute force solution for this. Can you please provide me the case. And no my submission answered correct ans for all the cases that I made by my own.

Please check this [Editing test case]

@ashish1610 General advice for getting testcases where your code fails. As you have an AC, so I assume that you had a solution which was accepted, now what you can do is generate random test-cases and run both your AC and WA solutions and check where the solutions of both cases don’t match. This generally helps me, I dont know if this is a recommended thing or not but it has helped me a lot. In case I dont have AC solution with me, I use brute-force approach if my main aim is to know where it gets wrong.

I am assuming it is 1 1 rather than 1 1 15 in 2nd line and 2 3 15 rather than 3 3 15

It gave correct ans.

I am sorry Ashish. It seems I made a mistake in understanding your logic.

Expected 10, your program returns 9.
