How do I print a reverse string?

Strings can be reversed using slicing. To reverse a string, we simply create a slice that starts with the length of the string, and ends at index 0. The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward).

How do you keep a string in reverse?

Take a copy of the original string, then use std::reverse to inplace reverse the copy. Then you can do a comparison on the two. Make a copy of the string and then use the reverse function from the algorithm header. Are you sure that this helps the OP or any other reader.

4. Creating a new string.

Why does 1 reverse a string in Python?

Explanation : Extended slice offers to put a “step” field as [start,stop,step], and giving no field as start and stop indicates default to 0 and string length respectively and “-1” denotes starting from end and stop at the start, hence reversing string.
