Challenge
Your task is to write code that checks is a word is a palindrome.

So when given input

Madam i'm adam!

Your program should return true.
Hint: Ignore non-characters
Time limit: 1s

Goodluck

Hmm, I don't understand what you mean but I do know what palindrome is.

Never odd or even

Omo_to_dun, pleas explain, I am not really good with programmings/

python solution:

<code>
import time

def check_palin(st):
t1 = time.time()
stripped = ""
for ch in st:
if (ord(ch) > 64 and ord(ch) < 91) or (ord(ch) > 96 and ord(ch) < 123):
stripped += ch
t2 = time.time()
print 'running time is %f' %(t2-t1)

return stripped.lower() == stripped[::-1].lower()
</code>

Ideally I would have imported re so i can use regular expressions to strip any non-alphabet from the string instead of looping character by character.

hmm cool

A java solution

class Palindrome
{
	private static String currentString="Madam i'm adam!";
	
	public static void main(String[] args)
	{
		System.out.println(isPalindrome());
	}
	
	static boolean isPalindrome()
	{
		return isPalindrome(0, currentString.length()-1);
	}
	
	static boolean isPalindrome(int start, int end)
	{
		if(start >= end){
			return true;
		}
		
		char first  = Character.toLowerCase(currentString.charAt(start));
		char last   = Character.toLowerCase(currentString.charAt(end));
		
		if(Character.isLetter(first) && Character.isLetter(last))
		{
			if(first == last){
				return isPalindrome((start+1), (end-1));
			}else{
				return false;
			}
		}
		else if(!Character.isLetter(first))
		{
			return isPalindrome((start+1), end);
		}
		else
		{
			return isPalindrome(start, (end-1));
		}
	}
}

Again its coded the OO way for reuse so it could be much shorter,

@fayimora, can you explain?

Yeah sure, would be much easier if i just carpet bomb the code with comments, Before that, give me your own algorithm for checking if a string is a palindrome. What would you do, it doesn't matter if you can but it helps to have a solution in mind, Aiit am waiting, Do that while i bombad the code,

Fayimora, trust me with computer and codes I am not good but I do like to learn that is why I asked
