WebYour claim Merging in merge sort without using temporary arrays is unwarranted: the global array c is a temporary array. Implementing mergesort in place without temporary arrays is difficult and less efficient than other sorting methods. There is no need for 2 temporary arrays, one with a length of half - low suffices, but allocating it with ...
