hdu 4627 The Unsolvable Problem

A水题，渐渐发现没有快感了。。

求最小公倍数。

 1 #include<stdio.h>
 2 #define LL __int64
 3 int main()
 4 {
 5     int T;
 6     LL n,s;
 7     scanf("%d",&T);
 8     while(T--)
 9     {
10         scanf("%I64d",&n);
11         if(n==2){
12             printf("1
");
13             continue;
14         }
15         if(n%2){
16             printf("%I64d
",(n/2)*(n/2+1));
17             continue ;
18         }else {
19             s=n/2;
20             if(s%2){
21                 printf("%I64d
",(s-2)*(s+2));
22                 continue;
23             }else {
24                 printf("%I64d
",(s-1)*(s+1));
25                 continue;
26             }
27         }
28     }
29     return 0;
30 }
