07. Moving

РЕШЕНИЯ С WHILE:

function moving(input) {
    let width = Number(input[0]);
    let length = Number(input[1]);
    let height = Number(input[2]);
    let volume = width * length * height;
    let index = 3;

    while (true) {
        let box = input[index++];
        if (box === "Done") {
            console.log(`${volume} Cubic meters left.`);
            break;
        }
        volume -= Number(box);
        if (volume < 0) {
            console.log(`No more free space! You need ${Math.abs(volume)} Cubic meters more.`);
            break;
        }
    }
}

Решение със shift():

function moving(input) {
    let width = Number(input.shift());
    let length = Number(input.shift());
    let height = Number(input.shift());
    let volume = width * length * height;

    while (true) {
        let box = input.shift();
        if (box === "Done") {
            console.log(`${volume} Cubic meters left.`);
            break;
        }
        volume -= Number(box);
        if (volume < 0) {
            console.log(`No more free space! You need ${Math.abs(volume)} Cubic meters more.`);
            break;
        }
    }
}

Решение с shift() и тернарен оператор леко тарикатската:)

function moving(input) {
    let volume = Number(input.shift()) * Number(input.shift()) * Number(input.shift());

    while (input[0] !== "Done" && input.length !== 0) {
        volume -= Number(input.shift());
    }

    console.log(input[0] === "Done" ? `${volume} Cubic meters left.` :
        `No more free space! You need ${Math.abs(volume)} Cubic meters more.`);
}

РЕШЕНИЕ С FOR() ЛЕКО ТАРИКАТСКАТА:

function moving(input) {
    let volume = Number(input[0]) * Number(input[1]) * Number(input[2]);

    for(let i = 3; i < input.length; i++) {
        if (input[i] === "Done") {
            console.log(`${volume} Cubic meters left.`);
            break;
        }
        volume -= Number(input[i]);
        if (volume < 0) {
            console.log(`No more free space! You need ${Math.abs(volume)} Cubic meters more.`);
            break;
        }
    }
}

РЕШЕНИЕ БЕЗ ЦИКЪЛ:

function moving(input) {
    let volume = Number(input.shift()) * Number(input.shift()) * Number(input.shift()) -
        input.filter(a => a !== "Done").map(Number).reduce((a, b) => a + b, 0);

    console.log(volume >= 0 ? `${volume} Cubic meters left.` :
        `No more free space! You need ${Math.abs(volume)} Cubic meters more.`);
}
