WEEK 1
1. Write an HTML page including JavaScript that takes a given set of integer numbers and shows
them after sorting in descending order.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Sort Integers Descending</title>
</head>
<body>
<h1>Sort Integers Descending</h1>
<label for="numbers">Enter numbers (comma-separated):</label>
<input type="text" id="numbers">
<button onclick="sortDescending()">Sort Descending</button>
<p id="sortedNumbers"></p>
<script>
function sortDescending() {
var numbersInput = document.getElementById('numbers').value;
var numbersArray = numbersInput.split(',').map(Number);
numbersArray.sort(function(a, b) {
return b - a;
});
var sortedNumbers = numbersArray.join(', ');
document.getElementById('sortedNumbers').innerText = 'Sorted
Numbers: ' + sortedNumbers;
}
</script>
</body>
</html>
Output:
Sort Integers Descending
Enter numbers (comma-separated): Sort Descending
WEEK 2
Write an HTML page including any required JavaScript that takes a number from
one text field in the range of 0 to 999 and shows it in another text field in words. If
the number is out of range, it should show “out of range” and if it is not a number, it
should show “not a number” message in the result box.
