Activity Selection Problem Proof of Optimality for the Greedy Algorithm in the Activity Selection Problem We prove that the greedy strategy of always selecting the activity with the earliest finish time yields an optimal solution to the activity selection problem. The proof relies on two key properties: 1. Greedy-Choice Property Claim: There exists an optimal … Read more

In its simplest form, binary search works on a contiguous sequence with specified left and right indices, also known as the search space. It continuously narrows down the search range to eventually locate the target value or determine that it does not exist.
