Reverse a String Without Using Built-in Functions

Given a string ( s ), your task is to output a new string which is the reverse of ( s ). You must not use any built-in reverse functions or slicing techniques. Instead, implement the reversal by iterating through the string and prepending each character to a result string.

For example, if the input is hello, the output should be olleh.

inputFormat

The input consists of a single line containing the string ( s ). It can be an empty string or a string that includes spaces and punctuation.
