Yes sir i did after 6 attempts thought it was overflow

Thank You sir!

Okay, I think I can explain... One thing to notice that if two square overlaps then there length and breadth of one rectangle must cross the breadth and length of the other rectangle so we need to discard those and we should count only the where the dimension don't overlap as mentioned i.e solution of the integral equation above which is shows the conditions of non-overlapping squares and subtract those which were counted twice due to rotations if u need further explanation u can ask
