=====Problem Statement=====
The provided code stub reads and integer, n, from STDIN. For all non-negative integers i < n, print i^2.
=====Example=====
The list of non-negative integers that are less than n = 3 is [0,1,2]. Print the square of each number on a separate line.
0
1
4
=====Input Format=====
The first and only line contains the integer, n.
=====Constraints=====
1≤n≤20
=====Output Format=====
Print lines, one corresponding to each i.
# Enter your code here. Read input from STDIN. Print output to STDOUT
a=int(input())
for i in range(0,a):
    print((i*i))

# Enter your code here. Read input from STDIN. Print output to STDOUT
a=int(input())
for i in range(0,a):
    print((i*i))
