2108 - Find First Palindromic String in the Array.
Easy
Given an array of strings words
, return the first palindromic string in the array. If there is no such string, return an empty string ""
.
A string is palindromic if it reads the same forward and backward.
Example 1:
Input: words = [“abc”,“car”,“ada”,“racecar”,“cool”]
Output: “ada”
Explanation: The first string that is palindromic is “ada”. Note that “racecar” is also palindromic, but it is not the first.
Example 2:
Input: words = [“notapalindrome”,“racecar”]
Output: “racecar”
Explanation: The first and only string that is palindromic is “racecar”.
Example 3:
Input: words = [“def”,“ghi”]
Output: ""
Explanation: There are no palindromic strings, so the empty string is returned.
Constraints:
1 <= words.length <= 100
1 <= words[i].length <= 100
words[i]
consists only of lowercase English letters.
