i will use your concept but in a better way like:
there is no need to make any f() function to calculate
factorial.
some lines of code:
main()
{
int a,b;
cin >> a;
bool check=1; //'1' for correct and '0' for wrong answer
if(a!=1)
check=0;
else {
for(int i=2; i<=1000; i++) {
cin >> b;
if(a*i!=b) {
check=0;
break;
}
a=b;
}
}
if(check)
printf("correct");
else
printf("wrong");
}
// since factorial(1000) is a very large value, so another
container can be used but logic remains same
