Exercise: Associative Arrays, 4. Party Time

Здравейте, исках да се опитам да реша тази задача с обект и получих 60/100 на Judge.

Знам, че може да се реши по-лесно с масиви, направих го, и ми даде 100/100.

Ще се радвам да разбера къде греша в кода с обекти.

Junge Link : https://judge.softuni.org/Contests/Compete/Index/1306#3

Код 60/100 с обект:

function creatingPartyList(list) {
let reservations = {};
let member = list.shift();

while (member != 'PARTY') {

if (isNaN(Number(member[0]))) {
reservations[member] = 'Regular';
} else {
reservations[member] = 'VIP';
}

member = list.shift();
}

let guests = list.slice();

guests.forEach(guest => {
if (reservations[guest]) { delete reservations[guest]; }
});

let regularGuestsNotComing = [];
let vipGuestsNotComing = [];

let guestsNotCome = Object.entries(reservations);

guestsNotCome.forEach(guest => {
if (guest[1] == 'VIP') {
vipGuestsNotComing.push(guest[0]);
} else {
regularGuestsNotComing.push(guest[0]);
}
});
console.log(regularGuestsNotComing.length + vipGuestsNotComing.length);
vipGuestsNotComing.forEach(guest => { console.log(guest); });
regularGuestsNotComing.forEach(guest => { console.log(guest) });
}

Код 100/100 с обикновени масиви:

Тагове:

Здравей, пробелмът ти е, че няма как да имаш еднакви ключове в обекта. Ако наистина искаш да я решиш с обект кода за решението е - https://pastebin.com/TQbfWtQQ. Имай предвид, че този код е доста натаманяван, но въпреки това Judge ми даде 100/100.

Бих ти препоръчал да се предържаш към второто решение на задачата.

Успех!

Oops, yeah object can not have the same property more than once

Hint: Guest names are not unique. Only the first match is removed when receiving a name.

;-)

Crazy code from the good old times:

function partyTime(guests) {
    let guestListArr = guests.splice(0, guests.indexOf('PARTY'));
    let guestList = new Map();
    guestList.set('VIP', []);
    guestList.set('regular', []);
    guests.splice(1, guests.length - 1).forEach(x => {
        if (guestListArr.includes(x)) { guestListArr.splice(guestListArr.indexOf(x), 1) }
    });

    guestList.set('VIP', guestList.get('VIP').concat(guestListArr.filter(x => !isNaN(x[0]))));
    guestList.set('regular', guestList.get('regular').concat(guestListArr.filter(x => isNaN(x[0]))));
    console.log(guestList.get('VIP').length + guestList.get('regular').length);
    [...guestList].map(x => console.log(x[1].join('\n')));
}

function solve(input) {
    let partyIndex = input.indexOf('PARTY');
    let guestList = input.slice(0, partyIndex);
    let comingGuests = input.slice(partyIndex + 1);

    let reservationList = generateGuestList(guestList);

    comingGuests.forEach(guest => {
        let status = checkForVIP(guest);
        let correctList = status ? 'vip' : 'regular';
        let currentGuest = reservationList[correctList].find(g => g.guest === guest);

        if (status && currentGuest) {
            currentGuest.isHere = true;
        } else if (currentGuest) {
            currentGuest.isHere = true;
        }
    });

    let vipGuests = reservationList.vip.filter(g => !g.isHere);
    let regularGuests = reservationList.regular.filter(g => !g.isHere);

    console.log(vipGuests.length + regularGuests.length);
    vipGuests.concat(regularGuests).forEach(g => {
        console.log(g.guest);
    })

    function generateGuestList(guests) {
        let obj = {
            vip: [],
            regular: [],
        };

        guests.forEach(guest => {
            let guestObj = { guest, isHere: false };

            if (checkForVIP(guest)) {
                obj.vip.push(guestObj);
            } else {
                obj.regular.push(guestObj);
            }
        });

        return obj;
    }

    function checkForVIP(guest) {
        return !isNaN(Number(guest[0]));
    }
}
