Abu is Aladdin's pet monkey and above all is his best friend. On their way to find the lamp and were passing over a Lava lake through a wooden bridge. Abu, mischievous as always started jumping on the bridge side-ropes and suddenly his foot slips and he landed onto a `5xx5` square matrix B floating on the lava. In order to keep his balance, Abu transforms the given matrix to another matrix A using an operation T: Choose any two neighbouring numbers and add the same integer (x) to them. If matrix B is transformed from matrix A, find the number x?

[Note: Two squares are neighbours if they have a common boundary.]
