Algorithm
Input: A string s. Process: Reverse the string by swapping characters from the beginning with the end. Output: The reversed string. Pseudocode
Start with two pointers, left at the beginning and right at the end.
Swap the characters at these positions. Move left one step to the right and right one step to the left. Repeat until left meets or passes right.
Explanation of Logic Each language has its own methods for reversing a string, but they all follow the general idea of swapping elements or using built-in methods to reverse arrays or sequences.
Python
In Python, we'll use a list (since strings are immutable) to perform the swap operations.
' ' ' def reverse_string(s):
Convert string to a list for easy swapping
str_list = list(s) left, right = 0, len(str_list) - 1
Swap characters from the ends to the center
while left < right: # Swap characters str_list[left], str_list[right] = str_list[right], str_list[left] left += 1 right -= 1
Join the list back into a string
return ''.join(str_list) ' ' '
