Solution: Implement Two Stacks Using One Array

Understand how to design and implement two stacks sharing one fixed-size array in C#. Explore efficient stack operations including push and pop without resizing the array. This lesson helps you grasp a practical data structure pattern valuable for coding interviews by managing stack pointers and preventing overflow or underflow.

Statement

Design a data structure TwoStacks, that represents two stacks using a single list, where both stacks share the same list for storing elements.

The following operations must be supported:

  • push1(value): Takes an integer value and inserts it into the first stack.

  • push2(value): Takes an integer ...
