Mastering the Two-Pointer Greedy Pattern for Resource Allocation

This algorithmic problem teaches a powerful pattern that transforms brute-force solutions from O(N×M) to O(N log N) complexity: sort both arrays and use two pointers to assign the smallest sufficient resource to the least demanding requirement. This greedy strategy extends far beyond cookie distribution, providing a reusable approach to interview problems like matching workers to jobs, scheduling boats for rescue, and real-world resource allocation challenges.
