Python Assignment 4 Programming Solutions

Question 1
Take two numbers N and K as an input. Create a list L of length N and initialize it with zeros. Change the value to 1 of even indexes if k is even, otherwise change the value of odd indexes. Print list L in the end.(Consider 0 as even)
Input:
N
K
Output:
A list L
Example-
Input:
5
2
Output:
[1, 0, 1, 0, 1]

Solution:

N=int(input())
K=int(input())

L= []

if K%2!=0:
  for i in range(N):
    if i%2==0:
      L.append(0)
    else:
      L.append(1)

else:
  for i in range(N):
    if i%2!=0:
      L.append(0)
    else:
      L.append(1)
