20 0 3年数学高考题 (全国卷 )第 2 2题 ,一般认为应从杨辉三角中寻找解题灵感 ,但是笔者认为这道题若用二进制数的思想来解 ,会更符合题目本身的特点 .现将笔者的解法介绍如下 :原题　 1 设 {ａｎ}是集合 {2 ｓ+ 2 ｔ0≤ｓｔ,且ｓ,ｔ∈Ｚ}中所有的数从小到大排列而成的数列 , The 2022 mathematics college entrance examination question (National Volume) Question 22, generally believed that we should seek inspiration from the Yang Hui triangle inspiration, but the author believes that if this problem is solved with the idea of ​​binary numbers, it will be more in line with the characteristics of the topic itself. Now the author’s solution is described as follows: The original question 1 is set {an} is a set of {2 s + 2 t0 ≤ st, and s, t ∈ Z} in the array of all the numbers from small to large,
