subsequence- python
<p>Tried to get it started but can't seem to get the question right.</p>

<pre><code>def is_subs(seq1, seq2)
    # returns true if seq2 is a subsequence of seq1, false otherwise.
    # I need to use recursion. But can't use built in features.
</code></pre>

<p>Any thoughts?</p>

<pre><code>if seq== ():
    return false
if seq2== ():
    return true
</code></pre>

<p>This is what I got started as but seems wrong.</p>
