Pass two ints as parameter and return the sum of numbers.

Test cases:

Java solution:

public class Sum {
	
	public static void main(String[] args) {
		Sum.sum(10, 12);
		Sum.sum(1, 2);
		Sum.sum(2147483647, 1);
	}
	
	public static long sum(int a,int b){
		return (long)a + b;
	}
}

Javascript solution:

const sum = (a, b) => {
    return a + b;
}

console.log(sum(10, 12)); //22
console.log(sum(1, 2)); //3
console.log(sum(2147483647,1)); //2147483648
