I was trying to solve the question 699C Fence Painting during which I came across a interesting bug in C++ compiler which I couldn't figure out.
I tried to submit to same solution using three different versions of C++ and it gave different result on each run.
C++ 14 : The solution got accepted 173550755
C++ 17 : The solution gave wrong answer on testcase 3 173550802
C++ 20 : The solution got runtime error on testcase 3 173550866
MikeMirzayanov will you please look into the matter or clarify if I have made a mistake. Any kind of help will be appreciated.
