<h5 id="description" style="text-align: center;">Description</h5>
2+
<p>Digital personal assistants help people to drive cars, plan their day, buy something online. In a sense, they are simplified versions of artificial intelligence with whom you can talk.</p>
3+
<p>In this project, you will develop step by step a simple bot that will help you study programming.</p>
4+
<h5 id="objective" style="text-align: center;">Objective</h5>
5+
<p>For the first stage, you will write a bot who displays a greeting, its name, and the date of its creation. First impressions count!</p>
6+
<p>Your program should print the following lines:</p>
7+
<pre><code class="language-no-highlight">Hello! My name is {botName}.
8+
I was created in {birthYear}.</code></pre>
9+
<p>Instead of <code class="java">{botName}</code>, print any name you choose and replace <code class="java">{birthYear}</code> with the current year (four digits).</p>
10+
<h5 id="example" style="text-align: center;">Example</h5>
11+
<p>Output:</p>
12+
<pre><code class="language-no-highlight">Hello! My name is Aid.
13+
I was created in 2020.</code></pre>
14+
<p>You can change the text if you want but print exactly two lines.</p>
15+
<p>Next, we will use <strong>Aid</strong> and <strong>2020</strong> as your bot's name and its birth year, but you can change it if you need to.</p>

<h5 id="description" style="text-align: center;">Description</h5>
2+
<p>Keep improving your bot by developing new skills for it. We suggest a simple guessing game that will predict the age of a user.</p>
3+
<p>It's based on a simple math trick. First, take a look at this formula:</p>
4+
<pre><code class="java">age = (remainder3 * 70 + remainder5 * 21 + remainder7 * 15) % 105</code></pre>
5+
<p>The numbers <code class="java">remainder3</code>, <code class="java">remainder5</code>, and <code class="java">remainder7</code> are the remainders of division by 3, 5, and 7 respectively.</p>
6+
<p>It turns out that for each number ranging from <em>0</em> to <em>104,</em> the calculation will result in the number itself. This perfectly fits the ordinary age range, doesn't it? Ask the user for the remainders and use them to guess the age!</p>
7+
<h5 id="objective" style="text-align: center;">Objective</h5>
8+
<p>In this stage, you will introduce yourself to the bot. It will greet you by your name and then try to guess your age using arithmetic operations.</p>
9+
<p>Your program should print the following lines:</p>
10+
<pre><code class="language-no-highlight">Hello! My name is Aid.
11+
I was created in 2020.
12+
Please, remind me your name.
13+
What a great name you have, Max!
14+
Let me guess your age.
15+
Enter remainders of dividing your age by 3, 5 and 7.
16+
Your age is {yourAge}; that's a good time to start programming!</code></pre>
17+
<p>Read three numbers from the standard input. Assume that all the numbers will be given on separate lines.</p>
18+
<p>Instead of <code class="java">{yourAge}</code>, the bot will print the age determined according to the special formula discussed above.</p>
19+
<h5 id="example" style="text-align: center;">Example</h5>
20+
<p>The greater-than symbol followed by a space (<code class="java">&gt; </code>) represents the user input. Note that it's not part of the input.</p>
21+
<p><strong>Example 1:</strong> <em>a dialogue with the bot</em></p>
22+
<pre><code class="language-no-highlight">Hello! My name is Aid.
23+
I was created in 2020.
24+
Please, remind me your name.
25+
&gt; Max
26+
What a great name you have, Max!
27+
Let me guess your age.
28+
Enter remainders of dividing your age by 3, 5 and 7.
