Driver license challenge (python), one failed test case

Question

https://www.sololearn.com/coach/18?ref=app

I have one failed test case (the others four are green), I can't understand where the issue is.

The code:

me = input()
numagents = int(input())
others = input()

turntime=20

drivers = others.split()
drivers.append(str(me))

drivers.sort()
mypos=drivers.index(me)+1

turns = (mypos // numagents) + (mypos % numagents)

print(turns * turntime)

Answer 1

It failing the test cases when numagents=5
Output should 20 only for all positions but giving 40.

Answer 2

Sorry for the late answer.
I just tried my code with a sample input (and 5 agents) and It gives the correct answer if "My" name is either the first or the last in the order. So I don't know why you'd say It gives 40...

Answer 3

Federico Bianco
As you said it gives 20 for agents=1 or 5.
But there may be cases agents=2 or 3 or 4
For those check output, 40, 60, 80.

Answer 4

let say we have mypos = 1 and numagents = 3

so:
turns = 1/3 + 1%3 = 2/3
print ( 2/3* 20)

output = 13.333

and thats wrong. In your calculation you do not consider that all employees of the driver office finish at the same time every 20 min!

so better would be:

turns = int(mypos/numagents)
if mypos%numagents != 0:
turns += 1
print (turns * turntime)

result: 20
