Program:
/* ............... START ............... */
def reverse_string(input_str):
return input_str[::-1]
# Example usage:
original_str = "Hello, world!"
reversed_str = reverse_string(original_str)
print(reversed_str)
/* ............... END ............... */
Output
!dlrow ,olleH
The output represents the reversed string of the original input string. The program takes the input
string and returns a new string with the characters in the reverse order. In this case, the original
string "Hello, world!" is reversed to "!dlrow ,olleH".
Notes:
-
This is a Python program that takes an input string and returns the reverse of the string.
- The program defines a function called reverse_string() that takes a single argument input_str. Inside the function, the [::-1] slice notation is used to reverse the string. This means that the function returns a new string with the characters in the reverse order.
- In the example, the reverse_string() function is called with the input string "Hello, world!". The result is then stored in a new variable called reversed_str. The print() function is then used to output the value of reversed_str to the console.
- When the program is executed, it prints the reversed string "!dlrow ,olleH" to the console.
