case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid binary search tree, we can copy the min value from right subtree to delete node, to convert the problem into case 2 function Node(val) {return{ val, left:null, ri...

Thetdeletesubroutine deletes the data specified by theKeyparameter. TheRootPointerandComparisonPointerparameters perform the same function as they do for thetsearchsubroutine. The variable pointed to by theRootPointerparameter is changed if the deleted node is the root of the binary tree. Thetdelete...

When you use delete operator, the memory allocated for that object (node in this case) is being freed. In function deleteTree you find the node and dealocate it's memory, but thepointer to that node(from its parent node)isn't being reset to NULL,it "hangs"pointing to something other ...
then only part of the tree will be visited.twalk() calls the user functionactioneach time a node is visited (that is, three times for an internal node, and once for a leaf).action, in turn, takes three arguments. The first argument is a pointer to the node being visited. The struct...
堆的deleteMin操作需要O(logn)的时间复杂度的原因是因为堆是一种完全二叉树的数据结构,并且满足堆属性:对于每个节点i,其父节点的值小于等于节点i的值。 在堆中,最小的元素总是位于根节点,...
