题目大意：求小于n的与n不互质的数的和。题解：首先欧拉函数可以求出小于n的与n互质的数的个数，然后我们可以发现这样一个性质，当x与n互质时，n-x与n互质，那么所有小于n与n互质的数总是可以两两配对使其和为n，这也就是为什么当n大于2时欧拉函数都是偶数，知道这一点后，就可以计算出小于n与n互质的数的...

题目链接 测试提交 一、题意 求解$1\sim n$与$n$不互质的数的和。 二、欧拉函数解法 定义：欧拉函数是小于$n$的数中与$n$互质的数的数目。 例如$φ(8)=4$，因为$1,3,5,7$均和$8$互质。 \(sum(n)=\phi(1)+\phi(2)+\phi(3)+...+\phi(
