In this article, we will discuss different methods to reverse a string in C/C++/Java/Python. The process of reversing a string involves changing the order of the characters in the string so that the last character becomes the first character, and so on a string can be reversed using the following approaches.

• Method 1: By swapping the characters of the string
• Method 2: By using recursion
• Method 3: By using standard library functions

Consider the below I/O samples before you program to reverse a string.

Method 1: Reverse a string by swapping the characters

The algorithm used in this method to reverse a given string is:

• 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. Let the actual length be j.
• Repeat the below steps from i = 0 to the entire length of the string.
• rev[i] = str[j]
• Print the reversed string.
