Q#51: Reorder an array by x elements in Python

Given an array of size n, write a function to move x elements from the front to the end of the array.

For example:

#Given the following:
array = [2,4,6,8,10]
x = 3
#To shift 3 elements you would return:
[8,10,2,4,6]

ANSWER

This question tests our understanding of Python programming, specifically writing a function and understanding array/list structures.

Luckily for us in python we can adjust arrays in place if we index through every element using [:]. So the solution will just be to index through the whole array by the partitions [x:] and [:x].

def shift_array(array, x):
   array[:] = array[x:] + array[:x]
   return array
