Solution: Advanced Array Operations with Improved Performance

<?php
$arr = ['Person', 'Woman', 'Man', 'Camera', 'TV'];
$iterator = new ArrayIterator($arr);
// Question 1a: Find and display the first element in the array.
$firstElement = $iterator->current();
echo "First Element: $firstElement\n";
// Question 1b: Find and display the last element in the array.
$iterator->seek(count($arr) - 1);
$lastElement = $iterator->current();
echo "Last Element: $lastElement\n";
// Question 1c: Check if the array contains the word "Camera" and display a message accordingly.
$iterator->rewind();
while ($iterator->valid()) {
    if ($iterator->current() === 'Camera') {
        echo "Array contains 'Camera'.\n";
        break;
    }
    $iterator->next();
}
// Question 1d: Remove the element "Man" from the array and display the updated array.
$iterator->rewind();
while ($iterator->valid()) {
    if ($iterator->current() === 'Man') {
        $iterator->offsetUnset($iterator->key());
    }
    $iterator->next();

// Question 2: Implement error handling for removing an element that doesn't exist.
try {

} catch (OutOfBoundsException $e) {
    echo "Error: " . $e->getMessage() . "\n";
}
// Display the updated array.
$updatedArray = iterator_to_array($iterator);
