Given a set , find XOR of the XOR 's of all subsets. | Returns XOR of all XOR 's of given subset ; XOR is 1 only when n is 1 , else 0 ; Driver program
function findXOR ( Set , n ) { if ( n == 1 ) return Set [ 0 ] ; else return 0 ; } let Set = [ 1 , 2 , 3 ] ; let n = Set . length ; document . write ( " " + findXOR ( Set , n ) ) ;
