Display an integer array of [1, 2, 3, 4, 5, 6, 7] in the following format 1 4 6 2 5 7 3 The method signature takes in an array of integers and the number of columns. In the above example, noOfCols = 3.
The columns should contain equal number of elements as much as possible.
public static void main(String[] args) { // TODO Auto-generated method stub int[] nums = { 1, 2, 3, 4, 5, 6, 7}; Problem.printArr(nums, 5); } private static void printArr(int[] nums, int numCols) { int numRows = nums.length / numCols; int numLastRow = nums.length % numCols; if (numLastRow > 0) { numRows++; } int[][] matrix = new int[numRows][numCols]; int arrIndex = 0; for (int i = 0; i < numCols; i++) { for (int j = 0; j < numRows; j++) { // If we‘re on the bottom row and over the number // of items to be put on it just skip this iteration if ((j == numRows - 1) && i >= numLastRow) { continue; } matrix[j][i] = nums[arrIndex]; arrIndex++; if (arrIndex >= nums.length) break; } if (arrIndex >= nums.length) break; } arrIndex = 0; for (int i = 0; i < numRows; i++) { for (int j = 0; j < numCols; j++) { if (matrix[i][j] > 0) System.out.print(String.format("%3d", matrix[i][j])); if (arrIndex >= nums.length) break; } System.out.println(); if (arrIndex >= nums.length) break; } } }
