I am getting a run time error in all the test cases on submitting my code.
Here is my code-
Merge Sort - RunTime Error
Hey @LPLC0059, your code looks great. Just a small mistake is there :
Replace b=x.split(' ') with this line :
b=x.split()
And your code would run correctly 
I hope this clears your doubt 
Happy coding 
Code is working fine now, thank you. Is there any shorter way to take input from the user?
Yes there is a shorter way. Something like this :
n = int(input())
l = [int(i) for i in input().split()]
I hope this helps !
Happy coding 
In this way you don’t need to use more than 1 list and can easily take desired input from the user
