How to get select value changed in real time?

Question

css

Hello. There is such a design:

<select>
    <option>Раз</option>
    <option>Два</option>
    <option>Три</option>
    <option>Другое</option>
</select>
<input type="text" placeholder="Укажите это самое другое">

The CSS input is set to display: none. What code should I write in jQuery so that when the user selects the "other" item, this input is assigned display: block?
