Small Factorial
I think…

@vipin123
Lets take a=99.
what should be the factorial.
The answer will be so large(more than 140 digits) such that You would not be able to store it in any numeric data type.

try to store result in array multiply in array stored result

just insert value in array in reverse order
temp=n;
res=0; i=0;
while(temp--)
{
    while(A.length()){

       res+=temp*A[i];
        A[i++]=res%10;
       res/=10;
   }
   if(res)A[i++]=res;

}

End of code
