In a queue P is standing 15th from the front and Q is standing 21st from the last. R is standing between P and Q. There are 7 students between P and R whereas there are 6 students between R and Q. Total number of students in the queue are: Correct Answer 50

Drawing diagram according to the given information,

Total students = 14 + ‘P’ + 7 + ‘R’ + 6 + ‘Q’ + 20 = 50

Hence, “50” is the correct answer.

A Double-ended queue supports operations such as adding and removing items from both the sides of the queue. They support four operations like addFront(adding item to top of the queue), addRear(adding item to the bottom of the queue), removeFront(removing item from the top of the queue) and removeRear(removing item from the bottom of the queue). You are given only stacks to implement this data structure. You can implement only push and pop operations. What are the total number of stacks required for this operation?(you can reuse the stack)
