In a queue of children, Kashish is fifth from the left and Mona is sixth from the right. When they interchange their places among themselves, Kashish becomes thirteenth from the left. Then what will be Mona’s position from the right? Correct Answer 14<sup>th</sup>

In a queue of children, Kashish if fifth from the left and Mona is sixth from the right.

When they interchange their places among themselves, Kashish becomes thirteenth from the left.

So, Kashish’s new position is the same as Mona’s earlier position.

So, number of children in the queue = (5 + 13) = 18

Mona’s new position is the same as Kashish’s earlier position i.e., fifth from the left

So, Mona’s position from the right = (18 – 5) + 1 = 14th

Hence, ‘14th’ is the correct answer.

A double-ended queue supports operations like 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’s the time complexity of performing addFront and addRear? (Assume ‘m’ to be the size of the stack and ‘n’ to be the number of elements)
