Java / Programs
Write a Java program to find the subArray in an Integer Array that has maximum Sum of the elements.
public class FindSubArrayWithMaxSum { public static void main(String[] args) { // Creating a bucket of integer array with various test values for unit testing int[][] myArr = { { 0, 1, 2, 3, 4, 5, 6, 7, 8, 10, -11 }, { 1, 2, 3, 0, 4, 3, -1, 3, 5, 5, 6, 6, -2, 50 }, { -3, 0, -1 }, { 0, -1 }, {}, { -2 }, { 2 }, { 0 }, { 1, 2, 3, -1, 1, 2, 3, 4, 0, -1, 1, 1 } }; // For each of the above data set find the sumArray with Maximum sum IntStream.range(0, myArr.length).mapToObj(i -> myArr[i]).parallel() .forEach(FindSubArrayWithMaxSum::findMaxSumSubArray); } static void findMaxSumSubArray(int[] myArr) { if (myArr.length == 0) return; int positionI = 0, positionJ = 0; int tempPositionI = 0, tempPositionJ = 0; int maxSum, tempSum; maxSum = tempSum = myArr[0]; for (int i = 1; i < myArr.length; i++) { if (tempPositionI >= i || tempSum < 0) { tempPositionI = tempPositionJ = i; tempSum = myArr[i]; continue; } if ((tempSum + myArr[i]) >= tempSum) { tempSum += myArr[i]; tempPositionJ = i; } else if (i + 1 < myArr.length) { positionI = tempPositionI; positionJ = tempPositionJ; maxSum = tempSum; tempPositionI = i + 1; } } if (tempSum > maxSum) { positionI = tempPositionI; positionJ = tempPositionJ; maxSum = tempSum; } System.out.println( Arrays.toString(myArr) + " >> Start Position: " + positionI + " End Position: " + positionJ + ", Sum: " + maxSum); } }
