Reverse a String Without Slicing

Given a string s, your task is to reverse the string without using Python's slicing feature or the built-in reversed() function. Instead, you should construct the reversed string by processing each character one by one.

For example, if the input is hello, the expected output is olleh.

Note: You must implement the reversal manually without utilizing any shortcuts like slicing.

inputFormat

The input is provided as a single line from standard input (stdin) containing the string s which may include spaces.

outputFormat

Output the reversed string to standard output (stdout).

hello

olleh
