【PAT甲级】1059 Prime Factors (25 分) 题意: 输入一个正整数N(范围为long int),输出它等于哪些质数的乘积。 trick: 如果N为1,直接输出1即可,数据点3存在这样的数据。 如果N本身是一个质数,直接输出它等于自己即可,数据点4存在这样的数据。 AAAAAccepted code: 1#defineHAVE_STRUCT_TIMESPEC2#include<bits/...
Output Specification: Factor N in the format N = p1^k1* p2^k2*…*pm^km, where pi's are prime factors of N in increasing order, and the exponent kiis the number of pi-- hence when there is only one pi, kiis 1 and must NOT be printed out. Sample Input: 97532468 Sample Output:...

另外积累本题的建立素数表的技巧。思路很巧妙,先将所有的数置1,然后在一次i循环中(和上面一样,开方循环),再对所有i*j<50000的循环数i*j置零,因为这些数除1和自身外还有额外的两个因数(不一定是质数)。 #include<vector>vector<int>prime(50000,1);for(inti=2;i*i<50000;i++)for(intj=2;j*i<50000...
