Below are 2 submissions I made for the above mentioned CSES problem.
Question link -> https://cses.fi/problemset/task/1158
AC submission -> https://cses.fi/problemset/result/10353320/
Runtime error submission -> https://cses.fi/problemset/result/10353300/
The only difference between the submissions is that in the AC submission, I commented out (#define int long long). Otherwise everything else is exactly the same.
Could someone explain why this happens? Is it some fault in my code? or something wrong with CSES website?
btw, your submissions are not visible, but I think that, this is most likely due to a MLE kind of issue, cuz long long takes more memory than int, but I cannot say for sure, before seeing your code
for example assume, that you made a 1e4 x 1e4 array, so, a long long array of that size would be 64 * 1e8 bits => 800 mb (MLE) whereas, an int array would be 32 * 1e8 bits => 400 mb (limit is 512 mb, so it can pass)
ig you can check if something like this is happening...
