showa function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.

Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates.

Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following.

aaa has duplicates abc has no duplicates

Print a line like one of the above for each of the strings in test_dups.
