2108. Find First Palindromic String in the Array\
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.
Solution :
class Solution {
public String firstPalindrome(String[] words) {
for(int i=0; i<words.length; i++)
{
String s="";
int n=words[i].length()-1;
for(int j=n; j>=0; j--)
{
s+=words[i].charAt(j);
}
if(s.equals(words[i]))
{
return s;
}
}
return "";
}
}
