Approach 1: Using another String to store the reverse
- Since the string is entered as Command line Argument, there is no need for a dedicated input line
- Extract the input string from the command line argument
- Create a String to store the resultant reversed string, say reversedString
- Traverse through this String character by character using loop, in reverse order
- Now append each character into the resultant reversedString
- This is the required reversed string
Program:
Output:
In Python

Approach 2: Without using another String to store the reverse
- Since the string is entered as Command line Argument, there is no need for a dedicated input line
- Extract the input string from the command line argument
- Traverse through this String character by character using loop till half the length of the string
- Swap the characters from one end with the characters from the other end
- This is the required reversed string
Program:
Output:
