10220 wa confused

Post by zsepi » Tue Jun 17, 2003 1:51 am

i honestly don't know what could be wrong with my solution - i pregenerate the factorials (0! -> 1000! - not even stripping the zeros from the end), calculate the sums of the digits, the program runs in time (less than a second), but still it's wa.... there cannot be tricky cases, the standard input works fine, so do my handchecked examples... Is there a trick in the format of the input I missed? I mean, is the following description correct?
Input: one integer for each test case, input ends with EOF
Output: one integer per line
thanx in advance for ur help

Success is also easy to handle: You've solved the wrong problem. Work hard to improve.

It sounds like you're doing it right, and if you've handled the special case
of 0! correctly, there isn't much I can think of. You could post the code or send it to me and I'll be happy to check it for you.

Best regards

OK!

I`m not here to answer your question, but to make one...
Which king of variable did you use to keep the answer of the factorial.. I mean... its a pretty big number and I can`t make it work, well the biggest factorial I can answer is 25, rsrsrs...
Did you make a different way to work with that giant number??

Thanx Trinity

You can use precalc method for this problem.
For your reference see problem 324 - 500!

using array only 10000 , save the result into the array. that's linear time

I think I havent understood your question right. The output for 987 is 10206, which was posted by Mohammad Mahmudur Rahman. But if you want to know the value of 987! then PM me.
