// 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.
