Need help with some code (Number Pyramid)

redcardinal

I need help making a program that makes a pattern like this with 'for loops':

                1
              1 2 1
            1 2 3 2 1
          1 2 3 4 3 2 1
        1 2 3 4 5 4 3 2 1
      1 2 3 4 5 6 5 4 3 2 1
    1 2 3 4 5 6 7 6 5 4 3 2 1
  1 2 3 4 5 6 7 8 7 6 5 4 3 2 1
1 2 3 4 5 6 7 8 9 8 7 6 5 4 3 2 1

Sorry that didn't come out correctly, but it is supposed to look like this:

Start with something simple and work your way up to it! Given a number X, can you print out a SQUARE of characters that is X long by X wide?

For example:

4:
XXXX
XXXX
XXXX
XXXX

6:
XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX

2:
XX
XX

Now instead of X's, can you print out NUMBERS?

For example:

4:
1234
1234
1234
1234


6:
123456
123456
123456
123456
123456
123456

2:
12
12

/**

 */

final int ROWS = 9;

for (int n = 1, r = 1; r <= ROWS; ++r, n = 1) {
  String s = "";
  while (n < r)  s += n++;
  s = nf(int(s), ROWS - 1).replace('0', ' ');
  while (n > 0)  s += n--;
  println(s);
}

exit();

How about with X's AND numbers, in a triangle?

Like this:

4:
XXX1
XX34
X234
1234


6:
XXXXX6
XXXX56
XXX456
XX3456
X23456
123456

2:
X2
12

Hint: How many X's are you printing on the first line? How many X's less do you print on the next line, and the ones after that?

Thanks so much!

Don't use gotoloops code, it is too dense for you, rewrite it so it matches your skill level

100+plus for what Chirsir said. No homework should asked here.
