Chapter 11.2, Problem 13E

The tournament sort is a sorting algorithm that works by building an ordered binary tree. We represent the elements to be sorted by vertices that sill become the leaves. We build up the tree one level at a time we would construct the tree representing the winners of matches in a tournament Working left to right, we compare pairs of consecutive elements, adding a parent vertex labeled with the larger of the two elements under comparison. We make similar comparisons between labels of vertices at each level until we reach the root of the tree that is labeled with the largest element. The tree constructed by the tournament sort of , 8.14,17,3,9,27,11 is ilinstrated in part(a)ef the figure. Once the argestelementhbeendetermined. The leaf with this labelisrelabeled by -s,which is definedtobelessthanevery element The labels of all vertices on the path from this vertex up to the root of the tree are recalculated, as shown in part (b) of the figure.

This produces the second largest element This process continues until the entire list has been sorted.

13. Complete the tournament sort of the list 22,8, 14, 17,3,9,27, ii. Show the labels of the vertices at each step.
