Problem A: Shortest Increasing Path The solution relies on direct case analysis based on the relationship between two integers, start and target. When the destination value strictly exceeds the starting point, a two-step traversal is always sufficient. If the start is at least two units larger than the target, a valid three-step route can be co ...

Problem T1 Problem Statement Given n team members with their individual speeds a[i] and carrying capacities w[i], determine the maximum achievable team speed where faster members can assist slower ones. Solution Approach The key insight is that the answer exhibits monotonicity, making binary search applicable. If a target speed x can be achieve ...
