I am trying to apply an effective divide and conquer approach on a 2D array that is sorted row-wise, and column-wise. Starting from the bottom left cell in the matrix, my algorithm chooses either to move one cell up or one cell to right depending on whether k is > or < than the curr_cell.… Read More Divide and Conquer Approach on 2D Array

Is it possible to get the sum of an array using divide and conquer? I’ve tried it, but I always miss some numbers, or I calculate a number twice. int[] arr = new int[]{1,2,3,4,5}; public int sum(int[] arr) { int begin = 0; int end = array.length – 1; int counter = 0; while (begin… Read More Divide and conquer sum of array iterative
