Print the two-dimensional list mult_table by row and column. On each line, each character is separated by a space. Hint: Use nested loops. Sample output with input: 123,246,369 \begin{tabular}{l|l|l} 1 & 2 & 3 \\ 2 & 4 & \\ 3 & 6 & 9 \end{tabular} Code writing challenge activity demo 1 user_input= input() 2 lines = user_input.split (,) 3 4 \# This line uses a construct called a list comprehension, introduced elsewhere, 5 \# to convert the input string into a two-dimensional list. 6 \# Ex: 12,24 is converted to [[1,2],[2,4]] 7 8 mult_table =[[ int (num) for num in line.splitO) for line in lines]
