Solution: Implement Two Stacks Using One List

Explore how to design a data structure that uses one list to represent two stacks sharing space efficiently. Learn to implement push and pop methods for each stack while maintaining fixed size and constant time operations.

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 value and ...
