The Ds\Sequence::rotate() function is an inbuilt function in PHP which is used to rotate the sequence element by a given number of rotations.
Syntax:
void abstract public Ds\Sequence::rotate ( int $rotations )
Parameters: This function accepts single parameter $rotations which holds the number of rotations.
Return value: This function does not return any value.
Below programs illustrate the Ds\Sequence::rotate() function in PHP:
Program 1:
<?php // Create new Sequence $seq = new \Ds\Vector([1, 2, 3, 4, 5]);
echo ( "Original Sequence\n" );
// Display the Sequence elements print_r( $seq );
// Use rotate() function to rotate // the sequence elements $seq ->rotate(3);
echo ( "\nSequence after rotating by 3 places\n" );
// Display the Sequence elements print_r( $seq );
?> |
Output:
Original Sequence Ds\Vector Object ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 ) Sequence after rotating by 3 places Ds\Vector Object ( [0] => 4 [1] => 5 [2] => 1 [3] => 2 [4] => 3 )
Program 2:
<?php // Create new Sequence $seq = new \Ds\Vector([ "Geeks" , "for" , "Geeks" ,
"Computer" , "Science" , "Portal" ]);
echo ( "Original Sequence\n" );
// Display the Sequence elements print_r( $seq );
// Use rotate() function to rotate // the sequence elements $seq ->rotate(8);
echo ( "\nSequence after rotating by 8 places\n" );
// Display the Sequence elements print_r( $seq );
?> |
Output:
Original Sequence Ds\Vector Object ( [0] => Geeks [1] => for [2] => Geeks [3] => Computer [4] => Science [5] => Portal ) Sequence after rotating by 8 places Ds\Vector Object ( [0] => Geeks [1] => Computer [2] => Science [3] => Portal [4] => Geeks [5] => for )
