Problem Statement :

You are given two n-element arrays, a and b, with each component either being 0 or 1.

You can perform two types of tasks.

Pick an index I and set ai to 1-ai.

Re - arrange the array an as desired.

Calculate the smallest number of steps required to produce an equal to b.




Format of Input :

Evey test contains a number of tests. The first line includes a single numeric p (1<= p <=400), which represents the number of tests. The test cases are described following table.

Evey test case begins with a single integer n (1<= q <= 100) — the duration of the arrays a and b.

Each test case's second line contains n space-separated integers d1,d2,...,dq (ai is 0 or 1) representing the array x.

Evey test case's 3rd line contains n space-separated integer value e1,e2,...,eq (bi is 0 or 1) going to represent the array y.



Format of the Output :

Publish the littlest number of operations required to produce an exactly equivalent to b for every test case.
