# Parul has two sequences A1,A2,…,AN and B1,B2,…,BN. She views two

Question Parul has two sequences A1,A2,…,AN and B1,B2,…,BN. She views two sequences with length N as identical if, after they are sorted in non-decreasing order, the i-th element of one sequence is equal to the i-th element of the other sequence for each i (1≤i≤N).To impress Parul, Rohit wants to make the sequences identical. He may perform the following operation zero or more times: choose two integers i and j (1≤i,j≤N) and swap Ai with Bj. The cost of each such operation is min(Ai,Bj).You have to find the minimum total cost with which Rohit can make the two sequences identical.Input-The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.The first line of each test case contains a single integer N.The second line contains N space-separated integers A1,A2,…,AN.The third line contains N space-separated integers B1,B2,…,BN.OutputFor each test case, print a single line containing one integer ― the minimum cost, or −1 if no valid sequence of operations exists.Constraints -1≤T≤2,000 • 1≤N≤2⋅10⁴ • 1≤Ai,Bi≤10³*³ for each valid i • the sum of N over all test cases does not exceed 2⋅10³*².SubtasksSubtask #1 (15 points): -T≤20 -N≤20Subtask #2 (85 points): original constraints.Example Input3 1 1 2 2 1 2 2 1 2 1 1 2 2 Example Output-1 0 1 ExplanationExample case 1: There is no way to make the sequences identical, so the answer is −1−1.Example case 2: The sequence are identical initially, so the answer is 00.Example case 3: We can swap A1 with B2, which makes the two sequences identical, so the answer is 1.

## In programming languages that support concurrency with multithreading, you can access more than one control thread running in one

Question In programming languages that support concurrency with multithreading, you can access more than one control thread running in one program.Question: what will happen with respect to two threads that want to change the value of a variable that can be accessed together, with x = x 1, where x (integer, initial value: 0) is the name variable?It is assumed that each thread performs 100,000 operations as successively. Code a simple program and display the output to support your answer With Java Programming Language
