Left array rotation leetcode

This is a follow-up problem of finding minimum element in rotated sorted array without duplicate elements. We only need to add one more condition, which checks if the left-most element and the right-most element are equal. If they are we can simply drop one of them.
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). You are given a target value to search. If found in the array return its index, otherwise return -1.. You may assume no duplicate exists in the array.
void reverse(int left, int right, int * array) { int temp = 0; while (left<right) { temp = array [left]; array [left]= array [right]; array [right] = temp; left++; right--; } } void rotate(int * nums, int numsSize, int k) { k = k%numsSize; //不知道为何这里要加上这一句?
Nov 02, 2019 · Given an integer array arr, in one move you can select a palindromic subarray arr[i], arr[i+1], ..., arr[j] where i <= j, and remove that subarray from the given array. Note that after removing a subarray, the elements on the left and on the right of that subarray move to fill the gap left by the removal.
The problem in your algorithm is that you are not sure if you find the exact pivot when its value is repeated. For example for the array [8,9,2,2,4,5,6] your algorithm find as pivot the element in the 4th position (counting from 0 is the element 3).
問題原文 Given an integer array nums sorted in ascending order, and an integer target. Suppose that nums is rotated at some pivot unknown to you beforehand (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). You should search for target in nums and if you found return its index, otherwise return -1. E…

相对于33题,不重复的而言,该题边二分边去重,剩余代码与33题一致 为啥一致呢?对与去重后,只可能在当前二分的首尾存在相同值, 目标值若与首尾相同,则向左向右二分均可,若不同,则按不存在重复值处理啦
Solution; For iterative solution, we know postal order is visit children before parent so a stack could be apply here as a helper structure. Then, we can ' push left child from root until left most leaf into stack. then start pop node from the stack, however, if the current node which going to be pop out has right node we should start push all left nodes of the right child until to leaf.

Range Sum Query 2D The above rectangle (with the red border) is defined by (row1, col1) = (2, 1) and (row2, col2) = (4, 3), which contains sum = 8.
method : view given rotated array as origin array without rotation. first use binary search to find rotate pivot point ( smallest point in given array ) we find 0 in the given array, and index is 4 ( rotation = 4 ) do binary search again; add a new variable realmid (mid + rotation = 4) % length => origin middle point for example :

Example: Input:root=[4,2,6,1,3,null,null] Output:1 Explanation: Note that root is a TreeNode object, not an array. The given tree [4,2,6,1,3,null,null] is represented by the following diagram: 4 /\ 2 6 /\ 1 3 while the minimum difference in this tree is 1, it occurs between node 1 and node 2, also between node 3 and node 2.
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in the array.

Mar 06, 2014 · The reason I use an array to hold the same value is because Java can only passed by value. For example, For example, in a=1; void calculate ( int a ) { a=a+1; } System . out . println ( a); // the result is still 1 , not 2 In order to track sum value of each calculation and not return the value of sum, we should use a collection or a wrapper ...
