Story of Matrix

"$Happy$ $Diwali$" an awesome story by Nykterstein, today he wanted to tell you guys this awesome story, but he knew you guys would be annoyed reading the story rather than the problem. So, he decided to tell the awesome story only if you solve this problem. Consider a Matrix $M$ of size $N$x$N$ where $M[i][j]$ represents the element in $i$-th row and $j$-th column, with $1$ based indexing.
