Programming Challenges Question 1

Programming Challenges Question 

Write a program which will print the below structures according to the input provided to the program.
The program should accept 3 inputs in the form of numbers between 1 and 9, both inclusive (one number per line) and then generate the corresponding structures based on the input.
Suppose the following sequence of numbers is supplied to the program:
3
2
4

Then the output should be:
  1
 2 2
3 3 3
 1
2 2
   1
  2 2
 3 3 3
4 4 4 4
