  <center><h1>Bitcoin Script Challenge</h1></center>
  <div class="content-container">
    Did you know that bitcoin has its own, native smart contract language? <a href="https://en.bitcoin.it/wiki/Script" target="_blank">Bitcoin Script</a> is a <a target="_blank" href="https://en.wikipedia.org/wiki/Forth_(programming_language)">Forth</a>-like, stack-based langauge, where operations either consume or manipulate elements on the stack.
    <br><br>
    In this challenge, your task is to evaluate a bitcoin script. The remaining stack elements will serve as your <b style="font-weight:normal">password</b> to advance to the next Hac-Man level.
    <br><br>
    <b style="font-weight:normal; color: #00ff00;">Bonus Bounty:</b> bitcoin funds are locked to this script.
