### Removing Duplicate Characters from a String using Python#### Task Description:Write a Python program to take a string from the user and remove all the duplicate characters from it, while ensuring the order of characters remains the same.#### Example:Input: `"programming"`Output: `"progamin"`#### Explanation:In the provided example, the string `"programming"` has the following duplicate characters: `r`, `g`, and `m`. The program will remove the second occurrence of each duplicate character while preserving the order of their first appearances.#### Sample Solution Code:```pythondef remove_duplicates(input_string): seen = set() result = [] for char in input_string: if char not in seen: seen.add(char) result.append(char) return ''.join(result)# Taking input from useruser_input = input("Enter a string: ")print("String after removing duplicates:", remove_duplicates(user_input))```#### How it Works:1. **Initialization**: - `seen` is a set that will keep track of characters that have already appeared in the string. - `result` is a list that will store characters in the order they first appear.2. **Iteration Over Input String**: - The program iterates through each character of the input string. - If the character has not been seen before (`if char not in seen:`), it is added to the `seen` set and also appended to the `result` list.3. **Final Output**: - After the iteration is complete, the `result` list will contain all characters of the original string but without duplicates while preserving the original order. - The `result` list is then converted into a string using `join()` method and returned as the final result.#### Usage:1. **Run the Program**: Execute the Python script in a Python environment.2. **Input the String**: When prompted, enter the string from which you want to remove duplicate characters.3. **View Output**: The processed string with duplicates removed will be printed on the console.#### Additional Information:- This algorithm has a time complexity of O(n), where n is the length of the input string, making it efficient for moderately sized inputs.- The space complexity is also O(n), due to the extra storage required for the `seen` set and `result` list. This method ensures the order is preserved and duplicates are
