Question 1

How do I print a rectangle instead of a square?

Accepted Answer

Instead of both loops running up to N, the outer loop runs up to the 'height' variable, and the inner loop runs up to the 'width' variable.

Question 2

What makes the square pattern unique?

Accepted Answer

In a square pattern, the number of columns printed is constant and does not depend on which row is currently being printed.

Question 3

What is the time complexity of printing an N x N square?

Accepted Answer

The outer loop runs N times, and the inner loop runs N times. Therefore, the time complexity is exactly O(N^2).

Question 4

Why do we use System.out.print instead of println for the stars?

Accepted Answer

Using 'print' keeps the output on the same horizontal line. Using 'println' would output each star on a completely new line, ruining the grid.
