Problem 54430. factorial
There are really some cody problems related to factorial of n, e.g., 42667, 45184, 46054, and etc. It is interesting to ask why dont we just write the number n! down and do any kind of analysis later.
So this problem asks you to write it down as:
input 3: write 3!=6
input 5: write 5!=120
but n may be as large as 100 or even more. Write the result with no spaces.
