The solution quits because it's taking too long. 1e8 is too many?

Stephen Strickland2020年3月28日

The difference should essentially be zero i.e. the two averages equal. I wrote a successful script; run in my desktop environment but the tool won't accept my answer as valid.

Jasmine Bajajon 11 Apr 2020

It crashes every time, how to complete it?

Charles Abramson 25 Apr 2020

To get this right apparently you have to generate the random numbers exactly the same way as the answer key. When it tests your script it seeds the random number generator and then confirms whether your program gets EXACTLY the same result. However, if you generate the random numbers in any way different from the key, your answer will be "wrong" but is probably still correct.

There is a MatLab function that does it. Nice and easy.

Louis Repussardon 9 Oct 2020

Nice one

"1e8 N-sided dice" made me confused. I think it should be changed to "1e8-sided dice".

Ryan Chapmanon 27 Nov 2020

这个问题刹车的网站。1e8 is too big and the website blocks out my computer.

Victor Zarateon 11 Feb 2021

After multiple tries of submitting what i thought the correct answer and being met with "While evaluating the solution, the server encountered an error caused by temporary unavailability of MATLAB Service. Wait a few minutes for the MATLAB Service to return, and then rescore." what seemed to do the trick was what Marcel Dornbusch hinted in his comment.
Just make sure you do not output every bit of information in the code, and just output the answer.

please improve how the question is asked. It is unclear and takes a while to understand the question however, once understood the code to do it is easy

You roll N-sided dice 1e8 times. It takes a while for me to get this. Apart from it an easy question.

It's really confusing, but: you have a dice with N sides! and you roll this dice 1e8 times!
Since I checkt this, the solution was clear ...

不正确的!
I created a "step by step" solution that was not accepted. Then I reformulated this solution for compound formula end, voila, it was accepted.

Note that using rand() with round() will not produce the correct answer. There is another function that must be used instead.

Grey Bohron 3 Jul 2020

What can be used? I am a bit confused.

1e8 is too big for the Matlab website. It crashes every time I try it. I managed to find a solution on the full version so I put it in comments and cheated to pass it.

I discovered using a for loop doesn't work - too slow. Then I realised that randi can generate the required vector, doh!

Gabriel Gomeson 19 Mar 2020

Can anyone do that in a size smaller than 22? That was the smallest size I could get.
