Given an array A of N integers and two integers X and Y, find the number of integers in the array that are both less than or equal to X and divisible by Y.

Input

• The first line of the input contains an integer T denoting the number of test cases. The description of each test case follows.
• The first line of each test case contains three space separated integers: N, X and Y.
• The second line contains N space-separated integers A₁, A₂, ..., A_N denoting the array A.

Output

For each test case, output a single line containing the answer.

Constraints

• 1 ≤ T ≤ 10
• 1 ≤ N ≤ 10⁵
• 1 ≤ A₁, A₂, ... ,A_N ≤ 10⁹
• 1 ≤ X, Y ≤ 10⁹

Write a java program where a user enters and stores the average monthly rainfall figures (int) for three (3) towns over a year. The rows represent the months, and the columns represent the towns.

Calculate and print the total rainfall figures for each town, and the average rainfall for each month. Use a switch statement to print out the month name according to the column subscript value (E.g. if col = 0, then print January, col = 1 then print February, etc.) with the corresponding total alongside it.

write a simple application which takes data from the console and saves it to a file. The program should take the following data:

name, address and phone number. The program should have a menu which allows users to load data from previous sessions.

Write a simulation program for the fruit market. The farmer will be able to

produce different types of fruits (apple, orange, grape, and watermelon),

and put them in the market to sell. The market has limited capacity and

farmers have to stand in a queue if the capacity is exceeded to sell their

fruits. Consumers can come to the market any time and purchase their

desired fruits; and if the fruits they want to buy runs out, they are willing to

wait until the supply of that kind is ready. (Hint: implementing this market

will encounter the producer and consumer problem, and it probably needs

multiple buffers for different kinds of fruits).

Write a program called ReverseHello.java that creates a thread (let's call it

Thread 1). Thread 1 creates another thread (Thread 2); Thread 2 creates

Thread 3; and so on, up to Thread 50. Each thread should print "Hello from

Thread <num>!", but you should structure your program such that the

threads print their greetings in reverse order.
