How does a merge sort work

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. http://krishnanaidoo.com/hello-world/
