Can you solve this real interview question? Longest Mountain in Array - You may recall that an array arr is a mountain array if and only if: * arr.length >= 3 * There exists some index i (0-indexed) with 0 < i < arr.length - 1 such that: * arr[0] <
数列中找最长的“山形”subarray,即先递增再递减的子列。要求1-pass,O(1)的空间。 难度:medium 算法:DP 思路: 这题本来可以用两个指针按顺序找,因为最大山形数列不会有重叠。 由于刚做过另一道题LeetCode 53 求和最大的子列,也就同样用了动态规划的思路去做。这题的DP稍微复杂一点,除了记录山形数列还要记录...
Given an integer arraynums, returnthe length of the longeststrictly increasingsubsequence. Example 1: Input:nums = [10,9,2,5,3,7,101,18]Output:4Explanation:The longest increasing subsequence is [2,3,7,101], therefore the length is 4. ...
Given an arrayAof integers, return the length of the longest mountain. Return0if there is no mountain. Example 1: Input: [2,1,4,7,3,2,5] Output: 5 Explanation: The largest mountain is [1,4,7,3,2] which has length 5. Example 2: ...
