You will be given a two-dimensional array and a number and you are asked to find whether the given matrix is Toeplitz or not. A matrix is a Toeplitz matrix if every descending diagonal, going from left to right, has only one distinct element. That is, it should be in the form:
You will be given a function which will take
two-dimensional matrix as argument.
1 from the function if the matrix is Toeplitz, else return
3 < n,m < 10,000,000
n is the number of rows while
m will be the number of columns.
Sample Test Case:
Sample Input : 4 5 6 7 8 9 2 4 6 7 8 9 1 4 6 7 8 0 1 4 6 7 Sample Output : 1
This is code-golf, so the shortest answer in bytes wins.
