More FAQs in How to Print a Square Star Pattern
In a square pattern, the number of columns printed is constant and does not depend on which row is currently being printed.
The outer loop runs N times, and the inner loop runs N times. Therefore, the time complexity is exactly O(N^2).
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.
