Increasing Matrix Row X41891

Write a program that finds out whether a given matrix has an increasing row; that is, a row where each element (except the first) is strictly larger than the preceding one.

Input

The input presents first the dimensions of the matrix, non-negative integers m and n, both in the same line; then m lines follow, each containing n integers: each line is a matrix row.

Output

The first row of the matrix where all elements, except the first, are strictly larger than the preceding element, if some such row exists; the text "No increasing row found." otherwise.
