Hi Guys!, im new to the forum. I need a little help with encoding and decoding words. Here are my two methods for encoding and decoding. As of now the output is working for the encoding, but the decoding isnt.

So the "decode" part is not supposed to do the reverse of the "encode" part? In that case you need to tell us what the "decode" part is supposed to do, and how exactly it is not working.

The two methods are not inverses of one another ! What made you think the decode() method was the inverse of the encode() . The inverse of your encode() method is itself . The decode() method is a caesar cipher and the inverse of it is very very similar to itself.

the encode() method is supposed to reverse characters in a string, while the decode() method is supposed to turn the characters back into the original word.

When you say "turn... back into the original word", does that mean the word before you reversed its characters? If so then, no, it doesn't do that. And Richard already pointed out that the way to undo the "reverse the order of characters in the word" operation is simply to do it again. The code in your posted decode() method is irrelevant to that.

Or does it mean something else?
I agree. Here's the link:
