896. 单调数列 896. Monotonic Array 题目描述 如果数组是单调递增或单调递减的,那么它是单调的. 如果对于所有 i<=j,A[i]<=A[j],那么数组 A 是单调递增的.如果对于所有 i<=j,A[i]>=A[j],那么数组 A 是单调递减的. 当给定的数组 A 是单调数组时返回 true,否则返回 false. LeetCode896. Monotonic Array 示例 1: 输入:[1,2,2,3] 输出:true 示例 2: 输入:[6,5,4,…
An array is monotonic if it is either monotone increasing or monotone decreasing. An array A is monotone increasing if for all i <= j, A[i] <= A[j].  An array A is monotone decreasing if for all i <= j, A[i] >= A[j]. Return true if and only if…
这是悦乐书的第345次更新,第369篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第210题(顺位题号是896).如果数组单调递增或单调递减,则数组是单调的.如果对于所有i <= j,A[i] <= A[j],则数组A是单调递增的.如果对于所有i <= j,A[i] >= A[j],则数组A是单调递减的.当且仅当给定的数组A是单调的时,才返回true.例如: 输入:[1,2,2,3] 输出:true 输入:[6,5,4,4] 输出:true 输入:[1…

LeetCode:Search in Rotated Sorted Array Suppose a sorted array 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, other…
LeetCode:Remove Duplicates from Sorted Array Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constan…
