Web16 de sept. de 2014 · If we want to sort the n numbers, using the heap min we can do it in n+n*log (n) time, that is called the heap sort. Regarding the second point, if C is a constant, we can use the brute force approach as follows: Prepare an array\vector of size C, call it temp. For each number in n:, place it in the correct order in the temp array.
