You are given a sequence of 16N positive integers a1, a2, . . ., a16N · You may
shuffle this sequence in any way you choose, i.e. change it to any one of its
permutations. Then, let
x = (a1 Ð a2) & (az O a4) ® . ..® (a8N-1 O asN),
y = (a8N+1 Ð a8N+2) ® (a8N+3 O a8N+4) ® ...® (@16N–1 O a16N),
where ® and O denote bitwise AND and XOR respectively.
Find the maximum possible value of x – y.
