UserThe problem is an over simplification of the flow of liquid. $-$ A terrain is given as a grid of cells of random elevations. The grid is always odd sized and is always a square. $-$ A liquid is poured at the central cell. Water can flow only north$-$south or east$-$west; not diagnonally. $-$ At the first step, the water level is the same as the central cell. $-$ Water from one cell flows to a neighbouring cell if the level of water is equal to greater than the elevation of the neighbouring cell. $-$ When the water flows to the neighbouring cell, the level of water is maintained. $-$ If the water cannot flow to any new cell, the water level rises. $-$ The simulation stops when the water reaches the end of the domain. $-$ The output consists of the domain represented by $.$ and W representing dry and wet terrain.

Constraints: First line of the input has dimension n of $($n X n$)$ matrix. Followed by the matrix itself as shown below in the sample input.

I$\text{'}$m giving you one question base on data$-$strcture and one test case and answer. then ill givi one test case you have to ganarate the output
