Re: Errors/Warnings/Bugs

Could you try another browser?
With me the problem turns up in IE11, but not in Chrome or Firefox. (With seemingly random pages. By me the page affected behaved normal again after about 48 hours)
Please let us know the result.

Re: I do not know/remember my Recovery Key

You generated your recovery key on Sat, 25 Mar 2017, 23:56.30.
The only way to recover your account is to find back this key. I assume that you saved it somewhere.
If you don't find it back, your account is lost.

Re: Problem 420

Squaring a matrix has nothing to do with matrix addition.
What you can read there is that for some matrices A,B,C holds that $A=B^2$ but also $A=C^2$

Re: Problem 038

If you want to go up to 5 you have to concatenate 2469*1 and 2469*2 and 2469*3 and 2469*4 and 2469*5.
This gives 246949387407987612345

The alternative account could have been creyD_
That one has solved one more problem than creyD has solved now. The problems solved by creyD were also solved by creyD_.

Re: Problem 638

Yes it is a spoiler. And moreover it doesn't belong to Recreational.

Answer to your question: solving for small cases could reveal resources on the web.

Never, never put this kind of spoiler on a public resource again.

The only thing I did was enter in Google's search field: "uva online judge java".
Then the first few results gave what you needed.
Have fun.

Re: Statistics on problems solved so far

Hovering and showing which problems would result in too much text for those who have solved many problems. Instead what I have done is changed the colouring system when a problem is solved.

Re: Problem 615

This simple program tells you the answer: def primefactorcnt(n): res=0 f=2 while n>1: while n%f==0: n/=f res+=1 f+=1 return res cnt=0 for n in xrange(2,10000): k=primefactorcnt(n) if k>=5: cnt+=1 if cnt==1000: print n break
