# Question:
# Write a Python program which takes 2 digits, X,Y as input and generates a
# 2-dimensional array with these dimensions. 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.
# Example
# Suppose the following inputs are given to the program:
# 3,5
# Then, the output of the program should be:
# [[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]]
#
# Hints:
# Note: In case of input data being supplied to the question, it should be
# assumed to be a console input in a comma-separated form.
#
#
# Solution:
print((lambda x, y: [[i * j for j in range(y)] for i in range(x)])(*map(int, input().split(","))))
