A-1 Intersection Set of Prime Factors(c++题解,禁止有注释,请严格按找题目要求,输出末尾没有空格) 分数 20 作者 陈越 单位 浙江大学 Given a positive integer n. Select two distinct digits from the decimal repersentation(十进制表示)of n, we obtain another integer m. What is the size of the intersection set(交集)of the prime factors of n and m? For example, given n=623457198, its prime factor set is A = {2, 3, 7, 13, 380621}. Swapping 2 and 9 gives us m=693457128, of which the prime factor set is B = {2, 3, 7, 13, 109, 971}. Then the intersection set of A and B is {2, 3, 7, 13}, with 4 factors. Input Specification: Each input file contains one test case, which gives a positive integer n (10<n≤10 9 ). It is guaranteed that there are at least 2 distinct digits in n. Output Specification: Swap any pair of digits in n to obtain m, you are supposed to find the m with the largest intersection set of the prime factors of n and m. Output in a line the number of the prime factors in the intersection set, together with m. The numbers must be separated by 1 space, and there must be no extra space at the beginning or the end of the line. In case such an m is not unique, output the one with the smallest value. Sample Input: 623457198 Sample Output: 4 123457698 Hint: There are two m's with 4 common factors. Besides the one given in the problem description, we can also swap 6 and 1 to obtain 123457698. This number has a prime factor set {2, 3, 7, 13, 23, 29, 113}, and so the intersection set is also {2, 3, 7, 13}. This number is in the ouput because it is smaller than 693457128. 代码长度限制 16 KB 时间限制 400 ms 内存限制 64 MB 栈限制 8192 KB
