Array Capacity Capacity increase 1 analysis Capacity become double size analysis Example Applications Introduction of Stack Normally, mathematics is written using what we call in-fix notation: (3+4)×5−6(3+4)×5−6 Any operator is placed between two operands. The advantage is that it's ...
Algorithm for the Implementation of Queue using Array For Insertion: Step 1: Get the position of the first empty space ( value of the rear variable) Step 2: Assign the new value to position the rear in an array if the queue is not full. Step 3: Increment the value of the rear variab...
Dequeue algorithm Dequeue operation is little expansive here, we need to check few things like whether stacks2is empty or not (stacks2is for dequeuer operation). The basic idea is ifs2is empty we transfer all element ofs1tos2and pops2. The popped element is same as the dequeued one. Whe...

push(struct stack *s,int data){ if(isempty(s->q1)) EnQueue(s->q2,data); else EnQueue(s->q1,data); } Pop operation algorithmThe basic idea is to transfer n-1 elements (let n be the total no of elements) to other queue and delete the last one from a queue to perform the pop...
Stack Time Complexity For the array-based implementation of a stack, the push and pop operations take constant time, i.e. O(1). Applications of Stack Data Structure Although stack is a simple data structure to implement, it is very powerful. The most common uses of a stack are: To rever...
