几个疑问 不解 !!!#include <stdio.h> int main() { int n,i,ways; scanf("%d",&n); ways = 0; if(n%2 != 0)ways++; for(i = 1;i < n;i = i + 2) { if(n%i == 0) ways++; } printf("%d\n",ways); return 0; } 这个程序能AC !!! #include <stdio.h> int main() { int n,i,ways; scanf("%d",&n); ways = 0; if(n%2 != 0)ways++; for(i = 1;i < n;i = i + 2) { if (i * (i + 1) / 2 > n) //加了这个语句就WA ... break; if(n%i == 0) ways++; } printf("%d\n",ways); return 0; } 它保证构造的最小一个数大于等于1 !!! Wa ... Why !!! Followed by: Post your reply here: |
