# Apple and Orange

Prepare your favorite cup of coffee, because we are about to enter the fantastic world of Apple and Orange.

## The solution

To start developing the solution, the first step is to define the function that will manipulate the input data:

``````function countApplesAndOranges(s, t, a, b, apples, oranges) {}
``````

Next we will count how many apples fell in Sam's yard. To do this, we will use the `filter` function on the `apples` array and we will only consider apples that are at a distance greater than or equal to s (the starting point of Sam's house) and less than or equal to t (the end point of Sam's house). In the end, we will check the size of `apples` with the `length` method and store this value in the `appleCount` constant:

``````const appleCount = apples.filter(apple => (a + apple >= s && a + apple <= t)).length;
``````

To count the oranges we will follow the same logic, considering the oranges that are at a distance greater than or equal to s and less than or equal to t. After this operation, we will store this value in the constant `orangeCount`:

``````const orangeCount = oranges.filter(orange => (b + orange >= s && b + orange <= t)).length;
``````

Now that we have determined the number of apples and oranges that fell in Sam's yard (`appleCount` and `orangeCount`), let's display these values in the console:

``````console.log(appleCount);
console.log(orangeCount);
``````

## Final resolution

After following the step by step we have our final resolution:

``````// Function that counts how many apples and oranges fell in Sam's yard
function countApplesAndOranges(s, t, a, b, apples, oranges) {
// Checking how many apples fell in Sam's yard
const appleCount = apples.filter(apple => (a + apple >= s && a + apple <= t)).length;
// Checking how many oranges fell into Sam's yard
const orangeCount = oranges.filter(orange => (b + orange >= s && b + orange <= t)).length;
// Showing on the console the amount of apples and oranges that fell in Sam's yard
console.log(appleCount);
console.log(orangeCount);
}
``````
