#P11209. Bitwise XOR Condition Count
Bitwise XOR Condition Count
Bitwise XOR Condition Count
Given two sequences \(\{a_i\}_{i=1}^n\) and \(\{b_i\}_{i=1}^n\), process \(m\) queries. In each query, you are given an integer \(k\). For each query, compute the following sum:
[ S = \sum_{i=1}^n \bigl[ (a_i \oplus k) \le b_i \bigr] ]
Here, \(\oplus\) is the bitwise XOR operator, and \([P]\) denotes the Iverson bracket, which equals 1 if the predicate \(P\) is true and 0 otherwise.
Note: Some of the test cases are evaluated online.
inputFormat
The first line contains two integers \(n\) and \(m\) (\(1 \le n, m \le 10^5\) or appropriate limits as specified by the problem).
The second line contains \(n\) integers representing the sequence \(a_1, a_2, \dots, a_n\).
The third line contains \(n\) integers representing the sequence \(b_1, b_2, \dots, b_n\).
Then \(m\) lines follow, each containing one integer \(k\), representing a query.
outputFormat
For each query, output a single integer on a new line, the value of \(S = \sum_{i=1}^n \bigl[ (a_i \oplus k) \le b_i \bigr]\).
