Delete Node in a Linked List 该题的难点在于单链表没法删除节点,那么就仅仅能将该节点兴许全部节点的值前移覆盖当前节点的值。须要注意的是在移动到倒数第二个节点的时候在覆盖其值之后须要将其下一个节点指向 nullptr。 class Solution { public: void deleteNode(ListNode* node) {...
Delete Node in a BST(删除BST中的节点) 题目 解法 思路:这题的求解依然可以使用到递归的思想,给出一个根节点和key值,删除key值对应的节点,如果当前给出的根节点的val大于key值,那么就可以从把当前根节点的左子节点作为新的根节点,递归调用这个方法;如果根节点的val小于key值,则把当前根节点的右子树当做新...
