NIELIT 2022 April Scientist B | Section B | Question: 106
A single array $A[1 \ldots \text{MAXSIZE}]$ is used to implement two stacks. The two stacks grow from opposite ends of the array. Variables $\text{top 1}$ and $\text{top 2}$ $(\text{top 1 < top 2} )$ point to the location of the topmost element ... $(\text{top 2} = \text{MAXSIZE})$ $\text{top 1} = \text{top 2} - 1$
