3. Write а Pythоn functiоn build_div_queue(num_elements, divisоr). When cаlled, it should creаte a new Queue of length num_elements, such that the front element of the Queue is 1/divisor, the 2nd element of the Queue is 2/divisor, and so forth, with the rear (num_element-th) of the Queue is the value num_elements/divisor. Assume the Queue class is provided with the following methods: class Queue: def enqueue(self,item): # add an item to rear of queue ... def dequeue(self): # remove and return an item from the front of queue ... def is_empty(self): ...
