Challenge: Write your First Higher-Order Function

Problem statement

You need to create a higher-order function, arithmeticCalculator, which returns the result of an arithmetic function that has two parameters of type int and returns a value of type num.

In this challenge, you will assume that the following arithmetic functions have been declared:

num add(int a, int b) {
  return a + b;
}

num subtract(int a, int b) {
  return a - b;
}

num multiply(int a, int b) {
  return a * b;
}

num divide(int a, int b) {
  return a / b;
}

For instance, the arithmeticPrinter will take the add function as input and return its result.

Input

arithmeticPrinter has three parameters.

1. A function, f
2. An integer, x
3. An integer, y

The input will be a function and two integers that will be passed to the function.

Output

The output will be the result of the arithmetic function.

Sample input

add, 4, 9

Sample output

13
