Comment on Why does the for loop repeat in this recursion?

So you’re drawing a triangle of # that starts skinny in the top left and grows to the right with a height and width of n?

As an example, Height 3 would be:

#
##
###

I’m not following your questions, but the code seems pretty reasonable.

Sort:hotnew top

An example using a nested loop

$n = 3;

for ($i = 0; $i &lt;= $n; $i++) {
    for ($j = 0; $j &lt; $i; $j++) {
        echo '#';
    }
    echo "\n";
}

It’s supposed to be a pyramid but not my code. It’s an example of a recursive function from a CS50 lecture and I’m just trying to understand how the code works line by line.

  So is my example of Height 3 in line with your expectations?

    I wrote an equivalent version just using nested loops - reading it might help you understand why the recursion works the way it does.
