Given a 01 matrix M, find the longest line of consecutive one in the matrix. The line could be horizontal, vertical, diagonal or anti-diagonal. Example: Input: [[0,1,1,0], [0,1,1,0], [0,0,0,1]] Output: 3 Hint: The number of elements in the given matr…
传送门:点我 978. Longest Turbulent Subarray A subarray A[i], A[i+1], ..., A[j] of A is said to be turbulent if and only if: For i <= k < j, A[k] > A[k+1] when k is odd, and A[k] < A[k+1] when k is even; OR, for i <= k < j, A[k] > A[k+1] wh…
Longest Increasing Subsequence 最长递增子序列 子序列不是数组中连续的数. dp表达的意思是以i结尾的最长子序列,而不是前i个数字的最长子序列. 初始化是dp所有的都为1,最终的结果是求dp所有的数值的最大值. class Solution { public: int lengthOfLIS(vector<int>& nums) { int length = nums.size(); ) ; vector<); int max_num; ;i <…
Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example,Given[100, 4, 200, 1, 3, 2],The longest consecutive elements sequence is[1, 2, 3, 4]. Return its length:4. Your algorithm should run in O(n…
Longest Common Subsequence最长公共子序列: 每个dp位置表示的是第i.j个字母的最长公共子序列 class Solution { public: int findLength(vector<int>& A, vector<int>& B) { int len1 = A.size(); int len2 = B.size(); || len2 == ) ; vector<vector<,vector<)); ;i <=…
Leetcode 5. Longest Palindromic Substring(最长回文子串, Manacher算法) Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example 1: Input: "babad" Output: "bab" Note: "aba&q…
Given a string s, find the longest palindromic subsequence's length in s. You may assume that the maximum length of s is 1000. Example 1:Input: "bbbab" Output: 4 One possible longest palindromic subsequence is "bbbb". Example 2:Input:…
Level:   Hard 题目描述: Given an unsorted array of integers, find the length of the longest consecutive elements sequence. Your algorithm should run in O(n) complexity. Example: Input: [100, 4, 200, 1, 3, 2] Output: 4 Explanation: The longest consecutive…
