Thank your very much for all your help, my program worked with the for loops. After getting the duplicates, I also had to put those integers in order, but I have done it already.

However, I have another question,
How do you compare a word with itself to check if it is a palindrome?

Do I have to use a character array or a string array because the user has to give me that word and the program has to read it backwards to check if it is or not?

If anyone has an idea please let me know!
