This is a complete minisite that contains a visual representation of the "Sunset Hills" challenge.

This project was created using Bootstrap 4.5, HTML5, CSS3, and JavaScript. All logic & JavaScript DOM changes were custom coded for this project.

Sunset Hills is an array manipulation challenge: the sun is setting in the West, and from West to East the heights of each building is given in an integer array. Which of the buildings can see the sunset?

This challenge or a slight variation has been used by technology companies such as Amazon and was also featured on a Geeks for Geeks blog post titled “Amazon Interview Experience | Set 189 (For SDE-1)”

This is a basic form of the function that determines which buildings can see the sunset.

The minisite has a modified version of this function to work with the page animations & grid generation.

//sunset hills algorithm
function sunsetHills(buildingHeights) {
    let sunsetHillsOutput = new Array();
    let highestBuilding = 0;
    for (i = 0; i < buildingHeights.length; i++) {
        if (buildingHeights[i] <= highestBuilding) {
            sunsetHillsOutput.push(false);
            continue;
        }
        highestBuilding = buildingHeights[i];
        sunsetHillsOutput.push(true);
    }
    //output will be an array of booleans
    return sunsetHillsOutput;
}
