WebAssuming you're using a max heap represented as an array and inserting your max elements backwards into your output array/into the back of your array if you're doing it in-place, the worst case input for heapSort is any input that forces you to "bubble down" or reheapify every time you remove an element. Web5 de ago. de 2024 · Starts with heapify (): You are calculating the left and right of a heap element as- l = 2 * i; r = 2 * i + 1; Assume that i is 0. In that case, it will give l as 0 which is incorrect. It should be l = 2 * i + 1; r = 2 * i + 2; Here, if (largest != i) { std::strcpy (arr [largest], arr [i]); you are copying arr [i] to arr [largest].
