title: is there std::mismatch for two unequal sized vectors?
body: <p>I d like to compare two vectors where the second one might have more/less items than the first one. </p>
  
  <pre><code>v1 = 1,2,3,4,5
  
  v2 = 1,0,3,4,5,6
  </code></pre>
  
  <p>As far as I understood, <code>std::mismatch</code> woNT do the trick. How could I detect the missing element in the v1?</p>
  
  <p>Thanks in advance,</p>
