Fibonacci numbers {Fn, n ≥ 0} satisfy the recurrence relation (1) Fn+2 = Fn+1 + Fn, along with the initial conditions F1 = 1 and F0 = 0. The Fibonacci name has been attached to the sequence 0, 1, 1, 2, 3, 5, ... due to the inclusion in his 1202 book …
传送门:http://codeforces.com/contest/902/problem/D 本题是一个数学问题——多项式整除. 对于两个整数a.b,求最大公约数gcd(a,b)的辗转相除法的函数如下: int gcd(int a, int b) { ) return a; return gcd(b, a % b); } 一次辗转相除法将数对(a,b)转化成(b,a mod b),直至b=0. 对于多项式A(x),定义deg A(x)为多项式的次数.对于多项式A.B,定义多项式mod运算:若A…
