Question

Given an array of integers nums and an integer target, create a function that returns the two numbers such that they add up to target

Solution

Explanation

Initialise a recursive function, and return a result based on the following conditions:

1. Return result as null if n is equivalent to the length of array
2. Return result as an array of numbers, containing two values that sum up to target
3. Call findTarget with n incremented by 1.

Code

`

    function findTarget(array, n, target) {
        let result = null;
        if (n === array.length) return (result = null), result;
        return (
            (result = array.filter(
            (int, index) => index !== n && array[n] + int === target
            )),
            result.length ? [array[n], ...result] : findTarget(array, (n += 1), target)
        );
    }
