Solution: Implement Two Stacks Using One List

Explore how to design a data structure that manages two separate stacks in one fixed-size list. Learn to perform push and pop operations in constant time, handle overflow and underflow conditions, and understand the time and space complexity relevant for coding interviews.

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 ...
