Challenge: Implement Two Stacks Using One Array
Explore how to design a data structure that efficiently manages two stacks within one fixed-size array using JavaScript. Understand in-place push and pop operations for each stack, enabling you to solve common stack challenges in coding interviews.
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. ...
