2330. Valid Palindrome IV π
Description
You are given a 0-indexed string s
consisting of only lowercase English letters. In one operation, you can change any character of s
to any other character.
Return true
if you can make s
a palindrome after performing exactly one or two operations, or return false
otherwise.
Example 1:
Input: s = "abcdba" Output: true Explanation: One way to make s a palindrome using 1 operation is: - Change s[2] to 'd'. Now, s = "abddba". One operation could be performed to make s a palindrome so return true.
Example 2:
Input: s = "aa" Output: true Explanation: One way to make s a palindrome using 2 operations is: - Change s[0] to 'b'. Now, s = "ba". - Change s[1] to 'b'. Now, s = "bb". Two operations could be performed to make s a palindrome so return true.
Example 3:
Input: s = "abcdef" Output: false Explanation: It is not possible to make s a palindrome using one or two operations so return false.
Constraints:
1 <= s.length <= 105
s
consists only of lowercase English letters.
