hdu 4135 Co-prime(容斥原理)

http://acm.hdu.edu.cn/showproblem.php?pid=4135求连续区间[a,b]内与n互质的数的个数。因为a,b相当大，考虑用容斥原理。只需先求出[a,b]内与n不互质的数的个数，等于[1,b]内与n不互质的个数-[1,a-1]内与n不互质的个数。问题转化为求【1，m】内与n不互质的数的个数。先对n分解质因子，[1,m]内是n的质因子的倍数的那些数肯定与n不互质，但

先提取出质因子，然后根据容斥的奇加偶减就行了。。。#include #include #include #include #include #include #include #include #include #include #include #include #include #definemaxn1000005 #definemaxm3000005 #defineeps1e-10 #def
