CF165E Compatible Numbers

Two integers $ x $ and $ y $ are compatible, if the result of their bitwise "AND" equals zero, that is, $ a $ $ & $ $ b=0 $ . For example, numbers $ 90 $ $ (1011010_{2}) $ and $ 36 $ $ (100100_{2}) $ are compatible, as $ 1011010_{2} $ $ & $ $ 100100_{2}=0_{2} $ , and numbers $ 3 $ $ (11_{2}) $ and $ 6 $ $ (110_{2}) $ are not compatible, as $ 11_{2} $ $ & $ $ 110_{2}=10_{2} $ . You are given an array of integers $ a_{1},a_{2},...,a_{n} $ . Your task is to find the following for each array element: is this element compatible with some other element from the given array? If the answer to this question is positive, then you also should find any suitable element.
