Уродливое number — это положительное inteiro, простые множители которого ограничены числами 2, 3 и 5.

given inteiro n, return true, если n является уродливым numberм.

Exemplo:

Input: n = 6

Output: true

Explanation: 6 = 2 × 3

        return false
    }
    for _, factor := range []int{2, 3, 5} {
        n = keepDividingWhenDivisible(n, factor)

    for dividend%divisor == 0 {
        dividend /= divisor
    }
    return dividend
}

Algorithm

1️⃣

Если данное inteiro n неположительное, return false, так как неположительное number не может быть уродливым.

2️⃣

Определите функцию keepDividingWhenDivisible, которая принимает два аргумента: делимое и делитель. Эта функция будет делить делимое на делитель до тех пор, пока оно делится без остатка. Функция returns измененное делимое. Последовательно примените эту функцию к n с делителями 2, 3 и 5.

3️⃣

Если после всех делений n равно 1, return true, иначе return false.
