My XOR

You have given an array $A$ of length $N$ consisting of positive integers and an integer $X$. You have to find a pair of two integers in A such that the $XOR$ of the integers in that pair is equal to $X$. If multiple such pair are there, print a pair whose minimum value is minimum along all other pairs. i.e. If pairs are - (2,5) , (3,7), (4,8) print $2$ $5$ as 2 is minimum among all other pairs.
