Algorithm logic: According to the size of the node, set up the tree, output the root node of the tree, and reset this to the maximum value, and then refactor the tree.
Because some of the comparison logic is preserved in the tree, the number of comparisons is reduced.
Also known as tournament sorting, time complexity is O (NLOGN), because each value (n) requires a depth (LOGN) comparison of the tree.
