Saddle Point in a 5x5 Matrix

Given a (5 \times 5) matrix where each row has a unique maximum element and each column has a unique minimum element, find the saddle point. The saddle point is defined as the element which is the maximum in its row and simultaneously the minimum in its column.

For example, consider the matrix below:
( \begin{matrix} 11 & 3 & 5 & 6 & 9\ 12 & 4 & 7 & 8 & 10\ 10 & 5 & 6 & 9 & 11\ 8 & 6 & 4 & 7 & 2\ 15 & 10 & 11 & 20 & 25 \end{matrix} )
The saddle point is 8 (located at the 4th row and 1st column).

inputFormat

The input consists of 5 lines. Each line contains 5 space-separated integers representing one row of the matrix.

outputFormat

Output a single line containing the saddle point value. If no saddle point exists, output "NO".
