Problem: Baseball Game
Explore how to implement a stack-based solution in C++ for the baseball game scoring problem with special operations. Learn to manage scores using push, pop, and peek techniques while understanding the problem's last in, first out pattern. This lesson helps you apply stack concepts for efficient computation and prepares you to handle similar algorithmic challenges effectively.
We'll cover the following...
Statement
You are the scorekeeper for a baseball game with unusual rules. You begin with an empty score record.
You are given a list of string operations, where each operations[i] represents the
An integer
x: Record a new score ofx."+": Record a new score equal to the sum of the two most recent scores."D": Record a new score equal to double the most recent score."C": Invalidate and remove the most recent score from the record.
Return the sum of all scores remaining on the record after all operations have been applied.
Note: The test cases are constructed such that the final answer and all intermediate calculations fit within a
‑bit integer, and all operations are guaranteed to be valid.
