+# Palindrome
+A palindrome is a word, phrase, number or sequence of words that reads the same backward as forward. Punctuation and spaces between the words or lettering is allowed.
+
+## Steps
+### Step 1
+Reverse string.
+### Step 2
+Compare the reversed string to the original string, if they are equal this mean that string is palindrome.
+
+## Example
+
+### Single Word Palindromes
+- Civic
+- Level
+- Madam
+
+### Multiple Word Palindromes
+- Don't nod.
+- I did, did I?
+- My gym
+
+## Implementation
+- [C](../../../algorithms/C/strings/palindrome.c)
+- [C#](../../../algorithms/CSharp/src/Strings/palindrome.cs)
+- [Haskell](../../../algorithms/Haskell/strings/palindrome.hs)
+- [Java](../../../algorithms/Java/strings/palindrome.java)
