XOR has the following problem... assume array is 2,3,3,2,1,2 here the unique element is 1 but using XOR we get.... 2^3^3^2^1^2=3
XOR works only when all the elements except the unique element occur even number of times. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
