Problem specification: Let's consider a square grid with rows and columns, both numbered 1 through N. Each cell contains one integer. Let Ri denote the minimum value in the i-th row, and let Ci denote the maximum value in the i-th column. A grid is called nice if and only if the following condition holds true: max(R1, R2, R3, ....., Rn ) = min(C1, C2, C3, ...., Cn) You have to write a C program that reads a N X N grid from the user and determines if the grid is nice or not. Input specification: The first line of the input contains an integer N, denoting the size of the grid. You can assume that 0
