hdu 4627 The Unsolvable Problem

A水题，渐渐发现没有快感了。。

求最小公倍数。

#include<stdio.h>
#define LL __int64
int main()
{
    int T;
    LL n,s;
    scanf("%d",&T);
    while(T--)
    {
        scanf("%I64d",&n);
        if(n==2){
            printf("1
");
            continue;
        }
        if(n%2){
            printf("%I64d
",(n/2)*(n/2+1));
            continue ;
        }else {
            s=n/2;
            if(s%2){
                printf("%I64d
",(s-2)*(s+2));
                continue;
            }else {
                printf("%I64d
",(s-1)*(s+1));
                continue;
            }
        }
    }
    return 0;
}
