What does it mean to reverse a string?

How do I reverse print a string?
Method 1: Reverse a string by swapping the characters
- Input the string from the user.
- Find the length of the string. The actual length of the string is one less than the number of characters in the string.
- Repeat the below steps from i = 0 to the entire length of the string.
- rev[i] = str[j]
- Print the reversed string.
