Kids Learn data structure (11): Heap Sort (a) what is a heapThe heap is actually a completely binary tree, with any one of its non-leaf nodes satisfying the nature:KEY[I]KEY[I]>=KEY[2I+1]KEY>=KEY[2I+2],That is, any non-leaf node keyword is not greater than or less than the key of the child node.The heap is divided into large top piles and small top heaps, satisfying key[i]>=key[2i+1]key>=key[2i+2] called large top heaps, satisfying key[i](ii) The idea
functions consumes more memory from your computer, which can cause programs to fail when the recursion level is too deep, such as the 64-storey tower that needs to be calculated for a long time.Therefore, the program can be written directly to the following recursive form:#include using namespace std;int main () { int N, M; cin >> n >> m; int out = 0; for (int i = 2; i cout "the last person to dequeue is numbered (starting from 0):" return 0;} Kids

Many companies to work open is used by a fingerprint machine, in order to prevent employees to punch in, late to leave early and so on.
