Given a non-empty string s, you may delete at most one character. Judge whether you can make it a palindrome.
Example 1:
Input: "aba" Output: True
Example 2:
Input: "abca" Output: True Explanation: You could delete the character ‘c‘.
Note:
time: O(n), space: O(1)
class Solution { public boolean validPalindrome(String s) { int l = 0, r = s.length() - 1; while(l <= r) { if(s.charAt(l) != s.charAt(r)) return valid(s, l + 1, r) || valid(s, l, r - 1); l++; r--; } return true; } private boolean valid(String s, int start, int end) { int l = start, r = end; while(l <= r) { if(s.charAt(l) != s.charAt(r)) return false; l++; r--; } return true; } }
