If that's the case, lazy me just wants to then wrap this in an ArrayList and proceed as I did.

Yep, sorry! Fixed it.

I'm a patient man.

Hi humble,

I had the same problem for a while. I just came back to the problem and solved it and naturally now I'm having trouble reproducing the rounding errors. Can you show how you are attempting to solve the kata and I'll see if I can spot what's going on?

No worries. Many thanks for addressing the problem!

Having some issues with the Java translation of this kata. Some of the submission test are expecting negative totals, which by my understanding shouldn't be possible. The product should always be >= the lcm, so product - lcm should always be >= 0. The sum of these differences should also then be >= 0.

For the test case:

[[41743, 45], [224939, 89167], [361, 32], [371293, 48841]]
expected:<-359842187> but was:<36541296948>

I checked the results in Excel got 36541296948 for this input.

I also got some results that didn't match positive expected results:

For the test case:

[[2352637, 605], [274625, 1444], [107653, 196], [3179, 2924207]]
expected:<662596159> but was:<8471627606>

2352637 and  605:   product = 1423345385   lcm = 1423345385   diff =          0 
274625  and 1444:   product =  396558500   lcm =  396558500   diff =          0
107653  and  196:   product =   21099988   lcm =     430612   diff =   20669376
2924207 and 3179:   product = 9296054053   lcm =  845095823   diff = 8450958230

0 + 0 + 20669376 + 8450958230 = 847162760, which is the answer I got.

Am I misunderstanding the kata? Or is there some issue with the way the official solution is coming up with results?

Thanks for your time.

Awesome, thanks for the speedy reply!
