It has only one pointer TOP that points the last or top most element of Stack. Insertion and Deletion in stack can only be done from top only. Insertion in stack is also known as a PUSH operation. Deletion from stack is also known as POP operation in stack.Stack...
Insertion, deletion min/max, and build. Insertion: we insert the node into the leaf, and max(min)heapify the heap to restore the ordering, the worst case run time is O(nlogn). Deletion: swap the node that was intended to be deleted (usually the root for max or min element) with ...

The Queue allows you to add an element at the tail and retrieve a piece from the head, thus giving FIFO ordering. On the other hand, Stack is a LIFO data structure, Last In First out, i.e., the element added first will be the last one to go. ...
The '-' denotes a "gap", adeletion-- this sequence lacks (has lost) what the other has at this position. Alternatively, aninsertionhas occurred in the other sequence, i.e. it has an additional position. (Bioinformatics' terminology; genes, mutation, evolution, common ancestor.) ...
Here is an offline algorithm which can solve this problem in O(N * sqrt(N) * log(N) + Q log Q). First we need a data structure that can support: insert a number. delete a number. get the mode number. It can be solved easily by binary heap / balanced binary search tree. We ...
