Reverse a String without Built-In Methods

You are given a non-empty string. Your task is to output its reverse without using any built-in reverse methods or slicing shortcuts.

You should implement the reversal using an iterative approach. For example:

• If the input is hello, then the output should be olleh.
• If the input is Python, then the output should be nohtyP.
