IPO
Explore how to maximize investment capital by selecting profitable projects within constraints. Understand how to apply heaps to choose up to k projects efficiently and solve dynamic resource allocation problems common in coding interviews.
We'll cover the following...
Statement
An investor is looking to maximize their capital by undertaking a set of profitable projects. Due to limited time and resources, they can complete at most k distinct projects.
There are i has:
A profit of
profits[i]earned upon completion.A minimum capital requirement of
capital[i]needed to start the project.
The investor starts with an initial capital of c. After completing a project, its profit is immediately added to the investor's current capital.
The goal is to choose up to k different projects in a way that maximizes the investor’s final capital. Return the maximum capital achievable after completing these projects.
It is guaranteed that the answer fits within a 32-bit signed integer.
Constraints:
kcprofits.lengthcapitals.lengthprofits[i]capitals[i]
