A13629. Create The Teams

There are $n$ programmers that you want to split into several non-empty teams. The skill of the $i$ -th programmer is $a_i$ . You want to assemble the maximum number of teams from them. There is a restriction for each team: the number of programmers in the team multiplied by the minimum skill among all programmers in the team must be at least $x$ .

Each programmer should belong to at most one team. Some programmers may be left without a team.

Calculate the maximum number of teams that you can assemble.

The first line contains the integer $t$ ( $1 \le t \le 1000$ ) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ( $1 \le n \le 10^5; 1 \le x \le 10^9$ ) — the number of programmers and the restriction of team skill respectively.

The second line of each test case contains $n$ integers $a_1, a_2, \dots , a_n$ ( $1 \le a_i \le 10^9$ ), where $a_i$ is the skill of the $i$ -th programmer.

The sum of $n$ over all inputs does not exceed $10^5$ .

For each test case print one integer — the maximum number of teams that you can assemble.
