standard outputThere are three arrays *a*, *b* and *c*. Each of them consists of *n* integers. SmallY wants to find three integers *u*, *v*, *w* (0 ≤ *u*, *v*, *w* ≤ *n*) such that the following condition holds: each number that appears in the union of *a*, *b* and *c*, appears either in the first *u* elements of *a*, or in the first *v* elements of *b*, or in the first *w* elements of *c*. Of course, SmallY doesn't want to have huge numbers *u*, *v* and *w*, so she wants sum *u* + *v* + *w* to be as small as possible.

Please, help her to find the minimal possible sum of *u* + *v* + *w*.

Input

The first line contains a single integer *n* (1 ≤ *n* ≤ 10^{5}). The second line contains *n* space-separated integers *a*_{1}, *a*_{2}, ..., *a*_{n} — array *a*. The third line contains the description of array *b* in the same format. The fourth line contains the description of array *c* in the same format. The following constraint holds: 1 ≤ *a*_{i}, *b*_{i}, *c*_{i} ≤ 10^{9}.

Output

Print a single integer — the minimum possible sum of *u* + *v* + *w*.

Note

In the first example you should choose *u* = 3, *v* = 0, *w* = 2.

In the second example you should choose *u* = 1, *v* = 3, *w* = 1.
