给定一个字符串,切割字符串,这样每个子字符串是一个回文字符串. 要找出所有可能的组合. 办法:暴力搜索+回溯 class Solution { public: int *b,n; vector<vector<string> >ans; void dfs(int id,string &s,int len){ if(id>=n){ if(len>0){ vector<string>vt; vt.push_back(s.substr(0,b[0]+1));…

class Solution { public: bool isPalindrome2(int x) {//二进制 int num=1,len=1,t=x>>1; while(t){ num<<=1; t>>=1; len++; } len/=2; while(len--){ if((num&x==0)&&(x&1)!=0){ return 0; } x&=(~num); x>>=1; num>>=2; }…

LeetCode:Palindrome Partitioning 题目如下:(把一个字符串划分成几个回文子串,枚举所有可能的划分) Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. For example, given s = "aab",Return [ […

Given a string s, partition s such that every substring of the partition is a palindrome. Return the minimum cuts needed for a palindrome partitioning of s. For example, given s = "aab",Return 1 since the palindrome partitioning ["aa",…

Given a string S, find the number of different non-empty palindromic subsequences in S, and return that number modulo 10^9 + 7. A subsequence of a string S is obtained by deleting 0 or more characters from S. A sequence is palindromic if it is equal…
