What is the time complexity of “pushing” an element into a queue if you are given a pointer to both the head and the tail of the queue?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))
Question
What is the time complexity of “pushing” an element into a queue if you are given a pointer to both the head and the tail of the queue?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))
Solution
The time complexity of "pushing" an element into a queue if you are given a pointer to both the head and the tail of the queue is O(1). This is because you have direct access to the tail of the queue, so you can simply add the new element at the tail in constant time, regardless of the size of the queue.
