Tournament sort in Haskell, based on Scheme code by Stepanov and Kershenbaum. Tournament sort Tournament sort is a sorting algorithm. It improves upon the naive selection sort by using a priority queue to find the next element in the sort. In the naive selection sort, it takes O("n") operations to select the next element of "n" elements; in a tournament sort, it takes O(log "n") operations (after building the initial tournament in O("n")). Tournament sort is a variation of heapsort. Tournament replacement selection sorts are used to gather the initial runs for external sorting algorithms. Conceptually, an external file is read and
