Write a Python program which takes a string ‘s’ as input and which returns True if the string is duplicated and False otherwise. Example: if s = “HelloHello”, the function must returns True.
# function thet takes a string s as input and returns True if s is a duplicated string def is_duplicated_string(s): n = len(s) """ first we checks if the length of the string s is even or odd. If it's odd, it cannot be a duplicated string, so the function returns False. """ if n % 2 != 0: return False else: # splits the string into two halves, first_half and second_half, and checks if they are equal. half = n // 2 first_half = s[:half] second_half = s[half:] return first_half == second_half # Now we can use this algorithm: s1 = "HelloHello" is_duplicated = is_duplicated_string(s1) print(is_duplicated) # Output: True s2 = "HelloWorld" is_duplicated = is_duplicated_string(s2) print(is_duplicated) # Output: False
