B"After the mysterious disappearance of Ashish, his two favourite disciples Ishika and Hriday, were each left with one half of a secret message. These messages can each be represented by a permutation of size n . Let's call them a and b . Note that a permutation of n elements is a sequence of numbers a_1, a_2, ldots, a_n , in which every number from 1 to n appears exactly once. The message can be decoded by an arrangement of sequence a and b , such that the number of matching pairs of elements between them is maximum. A pair of elements a_i and b_j is said to match if: His two disciples are allowed to perform the following operation any number of times: A single cyclic shift to the left on any permutation c is an operation that sets c_1:=c_2, c_2:=c_3, ldots, c_n:=c_1 simultaneously. Likewise, a single cyclic shift to the right on any permutation c is an operation that sets c_1:=c_n, c_2:=c_1, ldots, c_n:=c_{n-1} simultaneously. Help Ishika and Hriday find the maximum number of pairs of elements that match after performing the operation any (possibly zero) number of times. The first line of the input contains a single integer n (1 <= n <= 2 cdot 10^5) -- the size of the arrays. The second line contains n integers a_1 , a_2 , ..., a_n (1 <= a_i <= n) -- the elements of the first permutation. The third line contains n integers b_1 , b_2 , ..., b_n (1 <= b_i <= n) -- the elements of the second permutation. Print the maximum number of matching pairs of elements after performing the above operations some (possibly zero) times. For the first case: b can be shifted to the right by k = 1 . The resulting permutations will be {1, 2, 3, 4, 5 } and {1, 2, 3, 4, 5 } . For the second case: The operation is not required. For all possible rotations of a and b , the number"...
