Solution: Sort Values in a Stack

Explore two methods for sorting values in a stack using C#—an iterative approach with a temporary stack and a recursive sorting technique. Understand how each solution works, including their time and space complexity, to enhance problem-solving skills for coding interviews.

Statement

Given a stack of integers, stack, sort its elements in ascending order. In the resulting stack, the smallest element should be at the top.

Constraints:

  • 11 \leq stack.length103\leq 10^3 ...
