PATA 1132 Cut Integer (20分)
Cutting an integer means to cut a K digits lone integer Z into two integers of (K/2) digits long integers A and B. For example, after cutting Z = 167334, we have A = 167 and B = 334. It is interesting to see that Z can be devided by the product of A and B, as 167334 / (167 × 334) = 3. Given an integer Z, you are supposed to test if it is such an integer.
Input Specification:
Each input file contains one test case. For each case, the first line gives a positive integer N (≤ 20). Then N lines follow, each gives an integer Z (10 ≤ Z <231). It is guaranteed that the number of digits of Z is an even number.
Output Specification:
For each case, print a single line Yes
if it is such a number, or No
if not.
Sample Input:
3
167334
2333
12345678
- 1
- 2
- 3
- 4
Sample Output:
Yes
No
No
- 1
- 2
- 3
题目大意:
给你一个数字Z,将Z对半分成A和B,如果Z/(A*B)是整数那就是对的,如果不能就是错的。注意AB的积可能是0。
#include<cstdio>

scanf("%d",&N);
for(int i=0;i<N;i++)

string s = to_string(Z);
int len = s.length();
int a = stoi(s.substr(0, len/2));
int b = stoi(s.substr(len/2));
if (a * b != 0 && Z % (a * b) == 0)
printf("Yes");
else
printf("No");
if(i!=N-1) printf("\n");
}
return 0 ;
