Write a program that prints a right-angled triangle and a X sign as follows:

1. As your first task, you will print a triangle whose border is made of * signs and the interior is #.
   1. Ask the user for n, the number of lines with # signs.
   2. If n is less than 1, display a warning and proceed to the second task.
   3. If not, print the right angled triangle with n lines of #. On each new line there should be one more # than the previous line. Note that the complete shape will have n+3 lines. See the sample output.
2. As your second task, you will print an X sign which is made of * signs.
   1. Ask the user for m, the number of lines of the X sign.
   2. If m is less than 3, display a warning and skip this task.
   3. If not, print the huge X sign made up of * characters. See the sample output.
