/* QUESTION 2:
	
	Write a javascript function that takes an array of numbers and a target number. 
	The function should find two different numbers in the array that, 
	when added together, give the target number. 

	For example: answer([1,2,3], 4)should return [1,3]

	let temp = [];
	let sumArray= [];
	let resultArray = [];
	
	for(let i = 0; i < array.length; i++) {

			temp.push(array[i], array[i+1]);
			sumArray.push(temp);
