1) Define a struct to represent a product item with the fields: name, ID, price. 2) Define two named instances: "Trousers" 012 100 and "Shirt" 345 85. 3) Write a function that takes as argument: one struct instance (e.g. item_1), a new value for the ID and new value for the price. The function will overwrite the previous values for the ID and price in the called struct instance. For example, you create struct instance item_1 with the value from point 2 "Trousers" 012 100. When you run the function, it will update the ID and price fields with the new values from the argument of the function. 4) Make sure to explain what the difference between mutable and immutable is, as comments in your Racket file.
