C++ recursive merge sort

WebA merge sort algorithm closely follows the divide-and-conquer paradigm: Divide the n-element sequence to be sorted into two subsequences of n/2 elements each. Sort the two subsequences recursively by re-applying merge sort. Merge the two sorted subsequences to produce the sorted answer. WebOct 14, 2011 · you will need to implement a non-recursive version of merge-sort algorithm. Arrange two nested loops to accomplish this task. The outer loop should provide the size of segments for merging. The inner loop should take care of selecting positions of segments. The inner loop should start at the left edge and move your segments to the right.
