After staring at my code for nearly 1 hour, and even comparing my code to someone's else i still couldn't know why my code gives wrong answer for some testcases, is it the way I'm taking the mod ?

UPD: Its actually 2 hours

I'm not able to hack someone from yesterday's Div 3. Because of the hack file size (300 kb) and the limit is (256 kb), while it's a valid test case.

I tried copy pasting it, but it didn't work.

In this problem I made a dp solution that gets MLE.

Then i added this piece of code.

    for (int i = 1 ; i < n ; i++){
        depee(i,0);
    }

Surprisingly, it worked and i got AC.

can you explain what happened?
