int search(int[] nums, int l, int r) { if (l == r) return l; int mid = (l + r) / 2; if (nums[mid] > nums[mid + 1]) return search(nums, l, mid); return search(nums, mid + 1, r); } 最后返回search(nums, 0, nums.length - 1)就可以了。 Problem 4: Leetcode ...

Given a binary search tree and the lowest and highest boundaries asLandR, trim the tree so that all its elements lies in[L, R](R >= L). You might need to change the root of the tree, so the result should return the new root of the trimmed binary search tree. Example 1: Input: ...
Can you solve this real interview question? Binary Search - Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -
Note: You may assume the interval's end point is always bigger than its start point. You may assume none of these intervals have the same start point. Solution: 1. 1st thing I come up with is to use binary search, but it has LTE problem ...
33. Search in Rotated Sorted Array for class2: we have many transformation of such problem: like find the smallest that larger ot equals to target, or the first value that satisfy the conditions, or the last value that not satisfiy conditions. ...
