# DA-Sort

You recently learned a new way to sort an array of numbers in your algorithms course. The algorithm sorts an array of numbers by repeatedly performing the Delete-and-Append operation. The Delete-and-Append operation consists of three steps:

1. Choose an element from the array.

2. Delete the chosen element from the array.

3. Append the chosen element to the end of the array.

Being a curious student, you wonder what is the minimum number of Delete-and-Append operations required to sort a given array.

## Input

The first line of input contains a single decimal integer $P$, ($1 \le P \le 100$), which is the number of data sets that follow. Each data set should be processed identically and independently.

Each data set consists of two or more lines of input. The first line contains the data set number, $K$, followed by a single space, followed by an integer $N$, ($1 \le N \le 1\, 000$), which is the length of the array to sort. The remaining lines in the dataset contains $N$ positive integers that comprise the array to be sorted, $10$ values per line, except for the last line which may have less than $10$ values. All the array elements are no larger than $10^9$. The same value may appear more than once in the array to be sorted.

## Output

For each data set there is one line of output. The single output line consists of the data set number, $K$, followed by a single space followed by an integer which is the minimum number of Delete-and-Append operations required to sort the array.
