Exercise 5 - Files and Arrays Write a program Transpose.java that reads a 2D array from a file and prints its transpose (rows and columns interchanged) to standard output. Your program should consist of the following methods: // Create and return a 2D array read from standard input public static int[][] readArray(String filename) // Print a 2D array to standard output public static void printArray(int[][] a) Spring 2021 2 of 5 Intermediate Programming with Data Structures (CMPS 212) // Transposes a 2D array in place public static void transpose(int[][a) The input file that your program should read consists of two numbers representing the number of rows (n) and number of columns (m) in the array, followed by n x m integers that represent the entries. For example, consider the file matrix1.txt containing the following: 43 12018-1 23 780-128 1 An invocation of the program using this input file might produce: 12 -1 7-12 0 2 88 18 3 0 1
