Problem Statement

Given are sequences of N integers each: $(A_1,A_2,\cdots,A_N)$ and $(B_1,B_2,\cdots,B_N)$.
Find $\sum_{1 \leq i < j \leq N} \min(A_i \oplus A_j, B_i \oplus B_j)$, where $\oplus$ denotes the bitwise XOR.

Input

Input is given from Standard Input in the following format:
N
$A_1 A_2 \cdots A_N$
$B_1 B_2 \cdots B_N$

Output

Print the answer.

Constraints

• $1 \leq N \leq 250000$
• $0 \leq A_i,B_i < 2^{18}$
• All values in input are integers.

1 2 3
4 5 6

Sample Output 1

4

• $\min(1 \oplus 2, 4 \oplus 5)=\min(3,1)=1$
• $\min(1 \oplus 3, 4 \oplus 6)=\min(2,2)=2$
• $\min(2 \oplus 3, 5 \oplus 6)=\min(1,3)=1$

Thus, the answer is 1+2+1=4.
