instead of the sample output of

with sample inputs of

I tried coding the solution and fixing it but it still gives me the same output:

A weirdly new bluetooth transmission protocol is being tested and rolled out. A bluetooth device's transmitter must be tuned to specific frequencies. The device is given K frequencies at which to transmit some signals. A bluetooth device for the new protocol can handshake to a particular transmitted signal frequency, fᵢ if and only if the device's frequency mᵢ is greater than or equal to fᵢ.

You have N bluetooth devices to be tested one at a time. For each bluetooth device introduced in the testing area, all K frequencies will be blasted simultaneously. You must count how many frequencies each device will handshake among the K frequencies.

Input Format

Input begins with a line containing two space-separated integers and , indicating the number of frequencies and number of bluetooth devices, respectively.

*K*lines follow, each containing a single integer

*fᵢ*, indicating the frequency of the

*ith*transmission signal, as described in the problem statement.

*N*lines follow, each containing a single integer

*mⱼ*indicating the frequency of the

*jth*device to enter the testing area.

Constraints 1 ≤ K, N ≤ 3 * 10⁵ 1 ≤

*fᵢ*,

*mⱼ*≤ 10⁹

Output Format

For each of the

*N*bluetooth devices, print a line containing a single integer indicating how many of the

*K*frequencies they can handshake.
