Question:

Write a function LShift(Arr,n) in Python, which accepts a list Arr of numbers

and n is a numeric value by which all elements of the list are shifted to left.

Sample Input Data of the list Arr= [ 10,20,30,40,12,11], n=2

Output Arr = [30,40,12,11,10,20]

Solution:

def LShift(Arr,n):

L=len(Arr)

for x in range(0,n):

y=Arr[0]

for i in range(0,L-1):

Arr[i]=Arr[i+1]

Arr[L-1]=y

print(Arr)
