Return Value: It is used to return a set which contains the xor of the current set with another set.
Below programs illustrate the Ds\Set::xor() function in PHP:
Program 1:
<?php // Declare a new set $a = new \Ds\Set([1, 3, 5]); // Declare a new set $b = new \Ds\Set([2, 3, 6]); // Print the xor of both set echo ( "xor of both set is: \n" ); print_r( $a -> xor ( $b )); ?> |
xor of both set is: Ds\Set Object ( [0] => 1 [1] => 5 [2] => 2 [3] => 6 )
Program 2:
<?php // Declare a new set $a = new \Ds\Set([2, 3, 6, 7, 8]); // Declare a new set $b = new \Ds\Set([2, 3, 5, 8, 9, 10]); // Print the xor of both set echo ( "xor of both set is: \n" ); var_dump( $a -> xor ( $b )); ?> |
xor of both set is: object(Ds\Set)#3 (5) { [0]=> int(6) [1]=> int(7) [2]=> int(5) [3]=> int(9) [4]=> int(10) }
