# A left rotation operation on an array of size  shifts each of the array's elements 1 unit to the left. 
# For example, if 2 left rotations are performed on array [1,2,3,4,5], then the array would become [3,4,5,1,2]

#Given an array of n integers and a number,d , perform d left rotations on the array. 
#Then print the updated array as a single line of space-separated integers.

def rotate(array, position):
    #print
    print (array[position:] + array[:position])
