include<stdio.h>
int fact(int p[],int q,int t){
t--;
int i,temp=0,x;
for(i=0;i<q;i++){
x=p[i]*t+temp;
p[i]=x%10;
temp=x/10;
}
while(temp>0){
q++;
p[q-1]=temp%10;
temp/=10;
}
if(t>1){
fact(p,q,t);
}
else{
printf("\n");
for(i=q-1;i>=0;i--){
printf("%d",p[i]);
}
}
}
int count(int x){
int p[200],t=x,q=0,i,j;
if(x==1){
printf("%d",x);
}
else{
for(i=0;t>0;i++){
p[i]=t%10;
t/=10;
q++;
}
fact(p,q,x);
} }
int main(){
int t,i,j,a[100];
scanf("%d",&t);
for(i=0;i<t;i++){
scanf("%d",&a[i]);
}
for(i=0;i<t;i++){
count(a[i]);
}
}
