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.
