MF( i ) = a ^ fib( i-1 ) * b ^ fib ( i ) ( i>=3) mod 1000000007 是质数 , 依据费马小定理 a^phi( p ) = 1 ( mod p ) 这里 p 为质数 且 a 比 p小 所以 a^( p - 1 ) = 1 ( mod p ) 所以对非常大的指数能够化简 a ^ k % p == a ^ ( k %(p-1) ) % p 用矩阵高速幂求fib数后代入就可以 M斐波那契数列 Time Limit: 3000/100…
#打印斐波那契数列的第101项 a = 1 b = 1 for count in range(99): a,b = b,a+b else: print(b) 方法2: #打印斐波那契数列的第101项 a = 1 b = 1 for i in range(2,101): if i == 100: print(a+b) b += a a = b-a…
