Toeplitz Matrix

Statement

Given an $m \times n$ matrix, determine whether it is a Toeplitz matrix. Return TRUE if it is, otherwise return FALSE.

A matrix is considered Toeplitz if every diagonal running from the top left to the bottom right contains identical elements. In other words, for every cell matrix[i][j], if both i + 1 and j + 1 are within bounds, then matrix[i][j] must equal matrix[i+1][j+1].

Note:

• What if the matrix is stored on disk and memory is limited such that you can only load at most one row of the matrix into memory at a time? ...
