( 6245 ) D XOR Construction PROGRAMMING bitmasks constructive algorithms data structures math trees

B"You are given n-1 integers a_1, a_2, ... , a_{n-1} . Your task is to construct an array b_1, b_2, ... , b_n such that: The first line contains one integer n ( 2 <= n <= 2 cdot 10^5 ). The second line contains n-1 integers a_1, a_2, ... , a_{n-1} ( 0 <= a_i <= 2n ). Additional constraint on the input: it's always possible to construct at least one valid array b from the given sequence a . Print n integers b_1, b_2, ... , b_n . If there are multiple such arrays, you may print any of them. "...
