Write a program that randomly generates a 20 x 20 two-dimensional array, board, of type int. an element board[i][j] is a peak (either a maximum or a minimum) if all its neighbors (there should be either 3, 5, or 8 neighbors for any cell) are less than board[i][j], or greater than board[i][j]. the program should output all elements in board, with their indices, which are peak. it should also output if a peak is a maximum or a minimum.
