A. Cosmic End
Find a number within a given range that is the product of three distinct primes.
Given the small constraitn (upper bound ≤ 100), precompute small primes and check all combinations of three distinct ones. The maximum third prime needed is around 100/(2×3) ≈ 16, so checking primes up to 19 suffices.

NowCoder 2024 Multi-University Contest Round 1: Problem Set Analysis
The contest comprised 11 problems with varying difficulty levels based on technical depth:
High Solvability (8/11): Problems A, B, C, D, H, I, J, K generally follow standard patterns.
Low Solvability (3/11): E, F, G involve complex nested algorithms or obscure insights.
The following sections detail the solutions for the most instructive prob ...
