Rows with minimal elements

Input

The first line contains two integers, $n$ and m~(1 \le n, m \le 100) — the number of rows and columns, respectively.

The next $n$ lines each contain $m$ integers representing the elements of the array. The absolute value of each element does not exceed $100$.

Rows and columns are numbered starting from $1$.

Output

Print, in increasing order, the numbers of all rows that contain the minimum element of the array.
