use two indentations to get a "code block", that will keep the spacing and "a bit special characters":

  1    -->   1 | 10 | 6 | 17
  
  2    -->   2 | 4 | 5 | 11
  
  10          >>here I am<<

or define code blocks with groups of 3 backticks: `

```
inside
```

will lead to :

inside

I didn't know it was so difficult to use spaces here :(

Hi,
Maybe a visual display of the queue and the tills will be helpful :

Q          T = 2         Sum

1    -->   1 | 10 | 6 | 17

2    -->   2 | 4 | 5 | 11

10

4

5

6

At the end:

T1 contains : 1 | 10 | 6      T1sum = 17

T2 contains : 2 | 4 | 5      T2sum = 11

Maybe somthing like that and emphasizing on the part that only empty q will get new customer will help
Maybe integrating the notes after Edit: in the details will help too

I hope that had been helpful

Hi, thanks for the feedback- do you have any suggestions for a clearer wording of the problem?

Hi, please re-read the instructions, a lot of people have solved it successfully with Python so I would guess you misunderstood the requirements slightly!
