Question:
Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.
Note: i=0,1.., X-1; j=0,1,��Y-1.

Suppose the following input is supplied to the program:
1,2,3,4,5,6,7,8,9
Then, the output should be:
1,3,5,7,9
1,9,25,49,81

Hints:
In case of input data being supplied to the question, it should be assumed to be a console input.

Solution:
values = raw_input()
numbers = [x for x in values.split(",") if int(x)%2!=0]
numbers = [int(x)**2 for x in values.split(",") if int(x)%2!=0]
print ",".join(numbers)
