Leetcode 3057. Employees Project Allocation

Assign employees (each with skills, availability, or cost) to projects (each with skill requirements, capacity, and value) to maximize total benefit or minimize cost while meeting every project's constraints and employee limits; the core challenge is a constrained optimization that typically reduces to bipartite matching/assignment with capacities and costs (solved via min-cost max-flow, flow with lower/upper bounds, or advanced DP).
