题目描述

There are nn astronauts working on some space station. An astronaut with the number ii ( 1in1 \le i \le n ) has power aia_i .

An evil humanoid has made his way to this space station. The power of this humanoid is equal to hh . Also, the humanoid took with him two green serums and one blue serum.

In one second , a humanoid can do any of three actions:

  1. to absorb an astronaut with power strictly less humanoid power;
  2. to use green serum, if there is still one left;
  3. to use blue serum, if there is still one left.

When an astronaut with power aia_i is absorbed, this astronaut disappears, and power of the humanoid increases by ai2\lfloor \frac{a_i}{2} \rfloor , that is, an integer part of ai2\frac{a_i}{2} . For example, if a humanoid absorbs an astronaut with power 44 , its power increases by 22 , and if a humanoid absorbs an astronaut with power 77 , its power increases by 33 .

After using the green serum, this serum disappears, and the power of the humanoid doubles, so it increases by 22 times.

After using the blue serum, this serum disappears, and the power of the humanoid triples, so it increases by 33 times.

The humanoid is wondering what the maximum number of astronauts he will be able to absorb if he acts optimally.

输入格式

The first line of each test contains an integer tt ( 1t1041 \le t \le 10^4 ) — number of test cases.

The first line of each test case contains integers nn ( 1n21051 \le n \le 2 \cdot 10^5 ) — number of astronauts and hh ( 1h1061 \le h \le 10^6 ) — the initial power of the humanoid.

The second line of each test case contains nn integers aia_i ( 1ai1081 \le a_i \le 10^8 ) — powers of astronauts.

It is guaranteed that the sum of nn for all test cases does not exceed 21052 \cdot 10^5 .

输出格式

For each test case, in a separate line, print the maximum number of astronauts that a humanoid can absorb.

说明/提示

In the first case, you can proceed as follows:

  1. use green serum. h=12=2h = 1 \cdot 2 = 2
  2. absorb the cosmonaut 22 . h=2+12=2h = 2 + \lfloor \frac{1}{2} \rfloor = 2
  3. use green serum. h=22=4h = 2 \cdot 2 = 4
  4. absorb the spaceman 11 . h=4+22=5h = 4 + \lfloor \frac{2}{2} \rfloor = 5
  5. use blue serum. h=53=15h = 5 \cdot 3 = 15
  6. absorb the spaceman 33 . h=15+82=19h = 15 + \lfloor \frac{8}{2} \rfloor = 19
  7. absorb the cosmonaut 44 . h=19+92=23h = 19 + \lfloor \frac{9}{2} \rfloor = 23
