The function below takes two parameters: a string parameter: CSV_string and an integer index. This string parameter will hold a comma-separated collection of integers: '111,22,3333,4'. Complete the function to return the indexth value (counting from zero) from the comma-separated values as an integer. For example, your code should return 3333 (not '3333') if the example string is provided with an index value of 2. Hint: you should consider using the split() method and the int() function.
