1. Recursive Call in Merge Sort coderanch.com

I have a doubt in recursive call. This is the merge sort algorithm. 1. dividing the array in to 2 parts. Sorting them separateley. 2. merging left array and right array if (low < high) { middle = low+high/2; mergesort(low, middle); // Call -1 mergesort(middle + 1, high); // Call - 2 merge(low, middle, high) } My input array is int ...

2. recursive merge sort, how does it work? forums.oracle.com

i am having trouble figuring out these two sttements in the code mergesort(a,tmpa,left,center);//1 mergesort(a,tmpa,center+1,right);//2 ie the recursive calls. when will the //2 be executed? . what will be the values of center+1,right at which it starts executing ? basically im having trouble with the recursive calling. i have had read the tutorials but those are for simple cases like factorial etc. ...

3. Recursion: Merge Sort ArrayIndexOutOfBounds Exception forums.oracle.com

/** * Recursive method which continually divides an * array in half, sorts each half, then merges * each half into a single sorted array. * * @param list The array to be sorted */ public static void mergeSort(int[]list, int n) { // Declare variables to step through // the low, high and list arrays int lowIndex; int highIndex; int listIndex; ...

4. Quick and Simple Recursive (merge sort) Question forums.oracle.com

I am unsure as to what the recursive calls are exactly doing. Does it call all three methods simultaneously? ( I don't think so). For instance say, arr with size 6, first index left = 0, and last index right = 5 then... mid = 2; passes arr, 0, 2 mid = 1; passes arr, 0, 1 left is !< right ...
