In computer science, peek is an operation on certain abstract data types, specifically sequential collections such as stacks and queues, which returns the value of the top ("front") of the collection without removing the element from the collection. It thus returns the same value as operations such as "pop" or "dequeue", but does not modify the ...
The basic operations on a deque are enqueue and dequeue on either end. Also generally implemented are peek operations, which return the value at that end without dequeuing it. Names vary between languages; major implementations include:
The operation of adding an element to the rear of the queue is known as enqueue, and the operation of removing an element from the front is known as dequeue. Other operations may also be allowed, often including a peek or front operation that returns the value of the next element to be dequeued without dequeuing it.
A van Emde Boas tree supports the minimum, maximum, insert, delete, search, extract-min, extract-max, predecessor and successor] operations in O(log log C) time, but has a space cost for small queues of about O(2 m/2), where m is the number of bits in the priority value. [3] The space can be reduced significantly with hashing.

This will likely break the min-max heap properties, therefore we need to adjust the heap. Compare the new key to its parent: If it is found to be less (greater) than the parent, then it is surely less (greater) than all other nodes on max (min) levels that are on the path to the root of heap.
