欧拉函数/莫比乌斯函数 嗯……跟2910很像的一道题,在上道题的基础上我们很容易就想到先求出gcd(x,y)==1的组,然后再让x*=prime[i],y*=prime[i]这样它们的最大公约数就是prime[i]了…… 当然我们完全没必要这样做……对于每个prime[j],计算在(1,n/pr.....

题意:S[n]与所有S[i](i互质,则为Prime S。求(S[n]/X)%M;
思路:由集合性质推得S[i+1]=S[i]+S[i-1],则S[i]是斐波那契数。从第五项开始,每项斐波那契为质数的条件为当且仅当它的项数为质数,因此采用素数打表的方法得到第k个Prime S的斐波那契数的项数。然后用矩阵乘法求出第k个S的值对应的下一个斐波那契数,然后枚举该斐波那契数,直到能被X整除。
