How do you find duplicate characters in a given string in C#


🤖 Code Explanation

This code is a simple program that counts the number of occurrences of each character in a string. It first creates a Dictionary object to store the characters and their counts. It then loops through each character in the string, checking if it is already in the Dictionary. If it is, the count for that character is incremented. If not, the character is added to the Dictionary with a count of 1. Finally, it loops through the Dictionary, printing out each character and its count if the count is greater than 1.
