title: How to define delta in a PDA
body: <p>I'm a little confused about PDA's and how to define the tuple. I have the language L = { 0^n1^n | n &gt;= 0 } and I know that PDA's are six tuple with Q, sigma, gamma, delta, q0, and F. I know how to define all of them except delta.</p>
  <pre><code>Q = ['q1', 'q2', 'q3', 'q4'] 
  sig = ['0', '1']
  gam = ['0', '$']
  delta = ?
  q0 = 'q1'
  F = ['q1', 'q4']
  </code></pre>
  <p>Can anyone help me understand how delta is defined?</p>
