水题，注意一个完全平方数的位置

#include <iostream>
#include <cstdio>
#include <cstring>
#include <algorithm>
#include <cmath>
using namespace std;
typedef long long LL;
LL n;
int main(){
int T,nc = 1;
scanf("%d",&T);
while(T--){
LL x,y;
cin>>n;
LL k1 = floor(sqrt(n));
if(k1*k1 == n) k1--;
LL k2 = k1+1;
LL mid = (k1*k1+1+k2*k2)>>1;
//cout<<k1<<" "<<k2<<" "<<mid<<endl;
printf("Case %d: ",nc++);
if(k2&1){
if(n>mid){
cout<<k2*k2-n+1<<" "<<k2<<endl;
}
else if(n == mid){
cout<<k2<<" "<<k2<<endl;
}
else {
cout<<k2<<" "<<n-k1*k1<<endl;
}
}

}

}
}
}

return 0;
