For example, givens="aab", Return1since the palindrome partitioning["aa","b"]could be produced using 1 cut. 解题思路: 因为是Hard,用上题的结果计算肯定是超时的,本题需要用dp的思路,开一个boolean[][]的数组计算i-j是否为palindrome,递推关系为s.charAt(j) == s.charAt(i) && isPal[j + 1]...
publicbooleanvalidPalindrome(String s){// 使用双指针intleft=0;intright=s.length()-1;while(left < right) {// 如果左右指针所在的字符不相等,那就删掉右边的或者删掉左边的字符,再判断if(s.charAt(left) != s.charAt(right)) {returnisPalindrome(s, left, right-1) || isPalindrome(s, left+1, ...
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","b"] could be produced using 1 cut. 现在有一个...
