Data Structures for Coding Interviews in C++

Challenge: Reverse First k Elements of Queue

Explore how to reverse the first k elements in a queue with boundary validation. Understand queue manipulation techniques and practice implementing this efficiently in C++ for coding interviews.

We'll cover the following...

Statement

Given a queue and a number k, reverse the order of the first k elements in queue. If k is less than 00, if k exceeds queue size, or if queue is empty, return NULL. Otherwise, return the modified queue.

Constraints:

  • 0≤0 \leq queue.length
