I suppose that explained

Because you didn't sort it properly. Should be sorted by points: descending (you have ascending) - its not written directly but you can show it in example.
And if points are equal should be sorted by name.

You are completly right, i will do it again, thanks :)

haha, this is JS version.

u r right~

my mistake

Why do the results have to be 10 or 12?
In both the cases first two clients would occupy both the windows, thus adding 2 seconds or 6 seconds respectively.
When both the clients are finished, the last client would start, adding 10 more seconds.
Thus, the result would be 12 or 16 seconds respectively.

I forget that it's not recommended to jump from the queue.

Refreshing the page would helps.

Hi, the front of the queue is the first element in the array, so it should be:

Test.assertEquals(queueTime([2,2,10], 2), 12);
Test.assertEquals(queueTime([6,6,10], 2), 16);

Let me know if you have any further questions. I may add an example test case like these, as a few people seem to be having similar confusion.

thanks!

how about this ?

Test.assertEquals(queueTime([2,2,10], 2), 10);
Test.assertEquals(queueTime([6,6,10], 2), 12);

not deal with '-123'
