+  <p>Imagine that you are a hacker and you have got access to a web server written in Python. The problem is that it asks for a password that you do not know. However, this server is open source so you know that there is the <code class="language-python">wrong_password()</code> function which takes a password and checks it against <code class="language-python">real_password</code>.</p> 
+  <pre><code class="language-python">def wrong_password(password):
+    return (password == "" or (not password and real_password)) or password != real_password</code></pre> 
+  <p>You can not access the <code class="language-python">real_password</code> variable but you can call the <code class="language-python">wrong_password()</code> function and exploit its vulnerability to obtain the password. Write your code inside the <code class="language-python">solve()</code> function. Think about an argument that can be passed to the <code class="language-python">wrong_password()</code> function so that the function returns the <code class="language-python">real_password</code>. <strong>Print</strong> the result of the <code class="language-python">wrong_password()</code> function.</p> 
+  <p>Your program should not read any input or call the <code class="language-python">solve()</code> function, your task is to implement it.</p>
