Problem 6. Sum of 5 Numbers

let input = [
    '1',  // the input is always a string, so it's '3' and not 3
    '2',
    '3',
    '4',
    '5'
];
let print = this.print || console.log;
let gets = this.gets || ((arr, index) => () => arr[index++])(input, 0);

let number1 = +gets();
let number2 = +gets();
let number3 = +gets();
let number4 = +gets();
let number5 = +gets();

let sum = number1 + number2 + number3 + number4 + number5;

print(sum);
