Author USING LOOPS TO CREATE A PATTERN !
Jay Dean

2004-07-23, 3:57 am

Hi-
I am new to java and I would appreciate your help with a code
(method) using loops(while or for).It takes in an integer n, and
creates a triangle of n rows with alternating integers on each row.

Example 1: When n=4 the pattern below results:

...1...
..2.2..
.3.3.3.
4.4.4.4

Example 2: When n is say 3, the pattern below results:

..1..
.2.2.
3.3.3

I kind of see the pattern but can't seem to figure out how to
implement it with loops. I would appreciate any code that will help me
out.Thank you.

One way of thinking of it is this:

each line contains N characters. I need a loop that runs N times, the
canonical for.

I need M lines, I need an outer loop for that.


Now my question to solve is given i (row number) and j (the column
number) what character should I print? Hint look at the % operator.
