07 Company Users Exercise JavaScript Associative Arrays

Здравейте,

Имам проблем с една от задачите за домашно. Нулевите тестове минават, но Judge ми дава 60/100 и не мога да си открия грешката.

Може ли някой да провери? Предварително благодаря!

07.Company Users

Write a function which keeps information about companies and their employees.

You will receive array of strings containing company name and employee's id. Add each employee to the given company. Keep in mind that a company cannot have two employees with the same id.

When you finish reading data, order the companies by the name in ascending order.

Print the company name and each employee's id in the following format:

{companyName}

-- {id1}

-- {id2}

-- {idN}

Input / Constraints

The input come as array of strings, each in the format: "{companyName} -> {employeeId}".
The input always will be valid.

Използвай масив да пазиш id-тата, сега ползваш стринг с делиметер ',', но представи си имаш id което съдържа запетая (според мен това има в двата теста)

function solve(input) {
    let companies = {};
    for (const elem of input) {
        let [company, id] = elem.split(' -> ');
        if (!companies.hasOwnProperty(company)) {
            companies[company] = [];
        }
        companies[company].push(id);
    }
    let sorted = Object.entries(companies);
    sorted.sort((a, b) => a[0].localeCompare(b[0]));
    for (let elem of sorted) {
        console.log(elem[0]);
        let set = new Set(elem[1]);
        for (let number of set) {
            console.log(`-- ${number}`);
        }
    }
}

, после при сплита се изкривяват.

даже направо ги пази в сет, по-оптимално работи:

function solve(input) {
    let companies = {};
    for (const elem of input) {
        let [company, id] = elem.split(' -> ');
        if (!companies.hasOwnProperty(company)) {
            companies[company] = new Set();
        }
        companies[company].add(id);
    }
    let sorted = Object.entries(companies);
    sorted.sort((a, b) => a[0].localeCompare(b[0]));
    for (let elem of sorted) {
        console.log(elem[0]);
        for (let number of elem[1]) {
            console.log(`-- ${number}`);
        }
    }
}
