Below programs illustrate the Ds\Sequence::reverse() function in PHP:
Program 1:
<?php // Create new Vector $seq = new \Ds\Vector([1, 2, 3, 4, 5]); // Display the elements print_r($seq); echo("Sequence after reversing\n"); // Use reverse() function to reverse // the element and display it $seq->reverse(); print_r($seq); ?> |
Output:
Ds\Vector Object
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
Sequence after reversing
Ds\Vector Object
(
[0] => 5
[1] => 4
[2] => 3
[3] => 2
[4] => 1
)
Program 2:
<?php // Create new Vector $seq = new \Ds\Vector(["Geeks", "for", "Geeks", "Computer", "Science", "Portal"]); // Display the elements print_r($seq); echo("Sequence after reversing\n"); // Use reverse() function to reverse // the element and display it $seq->reverse(); print_r($seq); ?> |
Output:
Ds\Vector Object
(
[0] => Geeks
[1] => for
[2] => Geeks
[3] => Computer
[4] => Science
[5] => Portal
)
Sequence after reversing
Ds\Vector Object
(
[0] => Portal
[1] => Science
[2] => Computer
[3] => Geeks
[4] => for
[5] => Geeks
)
