Implement a Random Queue to randomly remove the books. This is an Implementation of the Queue interface in which the remove() operation removes an element that is chosen unl- formly at random among all the elements currently in the queue. The add(x) and remove() operations in a Random Queue should run in amortized constant time per operation You have to modify the file RandomQueue.py. Learning objectives: CLO 3 Hint: Use the random method randint from the module random to return random numbers. Test your Random Queue using the following tests. Remove one element from an empty Random Queue Add 5 elements and remove all, check that the remove operation return random values

The bonus rates for each salesperson are determined by sales amounts using the following scale: Sales greater than $35,000 earn a bonus rate of 5%, sales greater than $25,000 earn a bonus rate of 4%. All other sales (any amount greater than 0) earn a bonus rate of 2%. With the sheets still grouped, in cell C5 use an IFS function to determine the commission rate for the first salesperson whose sales are in cell B5. Fill the formula down through cell C8.
