The Ds\Map::xor() function is an inbuilt function in PHP which is used to create a new map which contains the value either in the first map or second map but not both.
Syntax:
Ds\Map public Ds\Map::xor ( Ds\Map $map )
Parameter: This parameter holds the other map of values.
Return value: It is used to return a map which contains the xor of the current map with another map.
Below programs illustrate the Ds\Map::xor() function in PHP:
Program 1:
<?php
$a = new \Ds\Map([ "a" => 1, "b" => 3, "c" => 5]);
$b = new \Ds\Map([ "a" => 2, "c" => 3, "d" => 6]);
echo ( "xor of both map is: \n" );
print_r( $a -> xor ( $b ));
?>
|
Output:
xor of both map is:
Ds\Map Object
(
[0] => Ds\Pair Object
(
[key] => b
[value] => 3
)
[1] => Ds\Pair Object
(
[key] => d
[value] => 6
)
)
Program 2:
<?php
$a = new \Ds\Map([ "a" => "Geeks" , "b" => "for" ,
"c" => "Geeks" ]);
$b = new \Ds\Map([ "b" => "Computer" , "e" => "Science" ,
"f" => "Portal" ]);
echo ( "xor of both map is: \n" );
print_r( $a -> xor ( $b ));
?>
|
Output:
xor of both map is:
Ds\Map Object
(
[0] => Ds\Pair Object
(
[key] => a
[value] => Geeks
)
[1] => Ds\Pair Object
(
[key] => c
[value] => Geeks
)
[2] => Ds\Pair Object
(
[key] => e
[value] => Science
)
[3] => Ds\Pair Object
(
[key] => f
[value] => Portal
)
)
