题目描述
Grigory has $ n $ magic stones, conveniently numbered from $ 1 $ to $ n $ . The charge of the $ i $ -th stone is equal to $ c_i $ .
Sometimes Grigory gets bored and selects some inner stone (that is, some stone with index $ i $ , where $ 2 \le i \le n - 1 $ ), and after that synchronizes it with neighboring stones. After that, the chosen stone loses its own charge, but acquires the charges from neighboring stones. In other words, its charge $ c_i $ changes to $ c_i' = c_{i + 1} + c_{i - 1} - c_i $ .
Andrew, Grigory's friend, also has $ n $ stones with charges $ t_i $ . Grigory is curious, whether there exists a sequence of zero or more synchronization operations, which transforms charges of Grigory's stones into charges of corresponding Andrew's stones, that is, changes $ c_i $ into $ t_i $ for all $ i $ ?
输入输出格式
输入格式
The first line contains one integer $ n $ ( $ 2 \le n \le 10^5 $ ) — the number of magic stones.
The second line contains integers $ c_1, c_2, \ldots, c_n $ ( $ 0 \le c_i \le 2 \cdot 10^9 $ ) — the charges of Grigory's stones.
The second line contains integers $ t_1, t_2, \ldots, t_n $ ( $ 0 \le t_i \le 2 \cdot 10^9 $ ) — the charges of Andrew's stones.
输出格式
If there exists a (possibly empty) sequence of synchronization operations, which changes all charges to the required ones, print "Yes".
Otherwise, print "No".

说明
In the first example, we can perform the following synchronizations ( $ 1 $ -indexed):
- First, synchronize the third stone $ [7, 2, \mathbf{4}, 12] \rightarrow [7, 2, \mathbf{10}, 12] $ .
- Then synchronize the second stone: $ [7, \mathbf{2}, 10, 12] \rightarrow [7, \mathbf{15}, 10, 12] $ .
In the second example, any operation with the second stone will not change its charge.
