External Sorting.Consider this sequence of 4S integers:

56 180 955 934 908 470 275 360 290 413

321 386 897 499 98 532 701 41 683 905

898 852 749 119 260 47 62 1 470 833

607 989 787 50 350 25 41 859 653 941

115 317 716 390 762

Use Multiway External Merge Sort to sort the integers into ascending order. Assume that your buffers can hold up to five integers each, and you have four buffers available. Show your collection of sorted runs at the end of each pass of the algorithm. Also, during passes 1-n, every fifth time you write out the content of the output buffer (that is, after the 5th, 10th, 15th, etc. writes), show the content of the input buffers at that time (the output buffer, having just be written, will be empty). That's how we'll be able to tell if you're following the algorithm correctly.
