[Challenge] palindrome counter

what is a palindrome? A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam or racecar. Challenge: write your shortest solution to determine how many palindromes are in a given input! eg. "abcdcba ghj 167h 1234ff4321" should output 2 (extra challenge for python user, it is possible in 1 line )

JavaScript: alert(prompt("").split(" ").reduce(function(a, b) { return b === b.split("").reverse().join("") ? a + 1 : a; }, 0));

Here's my C# implementation ✌ LINQ One-Liner〰 input.Split( new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries) .Count(w => w.SequenceEqual(w.Reverse())) Well C# LINQ can do it in one line too! Enjoy~ ❤ https://code.sololearn.com/ctD5q0gOi5I4/?ref=app
