Challenge: Implement Two Stacks Using One Array
Explore how to design and implement a data structure that handles two separate stacks within one fixed-size array. Understand operations such as push and pop for each stack without resizing the underlying array, and learn practical constraints for in-place management.
We'll cover the following...
Statement
Design a data structure TwoStacks, that represents two stacks using a single array, where both stacks share the same array for storing elements.
The following operations must be supported:
push1(value): Takes an integervalueand inserts it into the first stack.push2(value): Takes an integervalueand inserts it into the second stack.pop1(): Removes the top element from the first stack and returns it.pop2(): Removes the top element from the second stack and returns it.
Note: Perform all operations in-place without resizing the underlying list, maintaining a fixed size throughout. ...
