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.

WebSep 30, 2009 · The JavaScript interpreter has some kind of sort algorithm implementation built into it. It calls the comparison function some number of times during the sorting operation. The number of times the comparison function gets called depends on the particular algorithm, the data to be sorted, and the order it is in prior to the sort.
WebJan 1, 2024 · Merge sort works by successively merging two sorted list. The merging step is shown in the diagram above. The first elements of the two list are compared. The smallest is added to the merged set and this continues until the two lists are fully merge. The C++ code to do this is written as: WebDivide and conquer-based sorting algorithm Merge sort An example of merge sort. First, divide the list into the smallest unit (1 element), then compare each element with the adjacent list to sort and merge the two adjacent lists. Finally, all the elements are sorted and merged.
