stick lengths that can be produced, and find the smallest one, which is recorded as p. If p = 1, you don't need to do it anymore. Directly output-1. 2. all integers are divided into P classes by mod P values (mod p =, 4... p-1), as set q0, Q1, Q2...QP-1 if the set Qi has a length Len can be combined, then all the numbers in the set than Len can be combined. because it is mod P, Len can continually add P to combine numbers larger than it and in the same set as it. Based on this nature, we can
