Renovation

РЕШЕНИЕ С FOR:

function renovation(input) {
    let x = Number(input[0]);
    let y = Number(input[1]);
    let nonPaint = Number(input[2]);

    let paint = x * y * 4 - (x * y * 4 * nonPaint / 100);

    for (let i = 3; i < input.length; i++) {
        let painting = input[i];
        if (painting === "Tired!") {
            break;
        }
        paint -= Number(painting);
        if (paint <= 0) {
            break;
        }
    }

    if (paint > 0) {
        console.log(`${paint} quadratic m left.`);
    } else if (paint === 0) {
        console.log("All walls are painted! Great job, Pesho!");
    } else {
        console.log(`All walls are painted and you have ${Math.abs(paint)} l paint left!`);
    }
}

РЕШЕНИЯ С WHILE:

function renovation(input) {
    let index = 0;
    let x = Number(input[index++]);
    let y = Number(input[index++]);
    let nonPaint = Number(input[index++]);

    let paint = x * y * 4 - (x * y * 4 * nonPaint / 100);

    let painting = input[index++];

    while (painting !== "Tired!") {
        paint -= Number(painting);
        if (paint <= 0) {
            break;
        }
        painting = input[index++];
    }

    if (paint > 0) {
        console.log(`${paint} quadratic m left.`);
    } else if (paint === 0) {
        console.log("All walls are painted! Great job, Pesho!");
    } else {
        console.log(`All walls are painted and you have ${Math.abs(paint)} l paint left!`);
    }
}

Решение със swift():

function renovation(input) {
    let x = Number(input.shift());
    let y = Number(input.shift());
    let nonPaint = Number(input.shift());

    let paint = x * y * 4 - (x * y * 4 * nonPaint / 100);

    let painting = input.shift();

    while (painting !== "Tired!") {
        paint -= Number(painting);
        if (paint <= 0) {
            break;
        }
        painting = input.shift();
    }

    if (paint > 0) {
        console.log(`${paint} quadratic m left.`);
    } else if (paint === 0) {
        console.log("All walls are painted! Great job, Pesho!");
    } else {
        console.log(`All walls are painted and you have ${Math.abs(paint)} l paint left!`);
    }
}

Или леко тарикатската със shift() и с тернарен оператор:)

function renovation(input) {
    let x = Number(input.shift());
    let y = Number(input.shift());

    let paint = x * y * 4 - (x * y * 4 * Number(input.shift()) / 100);

    let painting;

    while ((painting = input.shift()) !== "Tired!") {
        paint -= Number(painting);
        if (paint <= 0) {
            break;
        }
    }

    console.log(paint > 0 ? `${paint} quadratic m left.` :
                paint === 0 ? "All walls are painted! Great job, Pesho!" :
                `All walls are painted and you have ${Math.abs(paint)} l paint left!`);
