[Leetcode] Binary tree--653. Two Sum IV - Input is a BST Given a Binary Search Tree and a target number, return true if there exist two elements in the BST such that their sum is equal to the given target. Example 1: Input: 5 / \ 3 6 / \ \ 2 4 7 Target = 9 Output: Tr...
note: the reason for the TLE problem is (1) the sort of lst and the binary search could also take extra time (2) the multiple duplicated cs search in t also take linear time. so wemay set up a dictionary to store every element ct and its index in t, then the search for cs in ...
Using recursion can usually make the code shorter and sometimes more readable. Using recursion in the algorithm can be very simply complete some functions that are not easy to implement with loops, such as the left, middle and right order traversal of a binary tree. ...
