Why is reversing letters used in programming?

• Checking if a string is a palindrome (a string that reads the same forwards and backwards).
• Data obfuscation for simple encryption techniques.
• Solving algorithmic problems that require manipulation of string order.

How can you reverse a string in Python?

Answer: In Python, a string can be reversed using slicing. Here’s an example:

original_string = "hello"
reversed_string = original_string[::-1]
print(reversed_string)  # Output: "olleh"

What are some common applications of reversed letters in real life?

Answer: Common applications of reversed letters include:

• Creating palindromic texts for artistic or linguistic purposes.
• Generating mirror images of text for printing or display.
• Basic encryption methods where reversing letters is one of the steps.

Can reversing letters affect the meaning of words?
