WebDownheap After replacing the root key with the key k of the last node, the heap-order property may be violated Algorithm downheap restores the heap-order property by swapping key k with one of its children along a downward path from the root. Which one? Downheap terminates when key k reaches a node whose children have keys greater … WebYour primary problem is this line of code: mino = (std::min(n->left, n->right)); Here, you're comparing two pointers when you really want to compare the values in the two objects you're referring to, and return a pointer to the object that has the smaller value.
