Given two arrays A and B consisting of N and M elements respectively. The task is to find minimum number of elements to remove from each array such that no common element exist in both the arrays.
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of three lines. First line of each test case contains two integers N and M denoting size of the arrays A and B respectively. Second line contains N space separated elements of array A and third line contains M space separated elements of array B.
Output: For each test case, print the minimum number of elements in new line.
