Write a 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.

public static bool has_Duplicates(string str)

       {

           str = str.ToLower(); // Lowercase all the items, makes them easier to sort

           int length = str.Length; // Get the length to apply to array

           char[] strArray = str.ToCharArray();

           // Turn to a character array

           Array.Sort(strArray);

           // Sort for speed and for method loop to work

           // Begin for loop to sort through letters

           for (int i = 0; i < length - 1; i++)

           {

               if (strArray[i] == strArray[i + 1])

               {

                   //if letter equals next letter, False

                   Console.WriteLine(str + "has duplicates");

                   return false;

               }

           }

           // if letter != next letter, Pass as True

           Console.WriteLine(str + "has no duplicates");

           return true;

       }
