[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 )

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~ ❤
