Clever invocation of a two-dimensional array!

A two-dimensional array that can accurately locate each item without i,j.

Look at someone else's code today, accidentally found others so with a two-dimensional array.

int arry[n];

int t=n;

int Arry[n][n]; int t=n;  for (t=0; t<n*n;t++) {arry[t/n][t%n];}

Note: The above code is not able to run, it is my simple expression

The key is to imagine that the two-dimensional array is a rectangular list, the line number is t/n, the column number is t%n;

Take a few of your own and slowly feel it.
