<p>You are given an integer array <code>nums</code> and a <strong>non-negative</strong> integer <code>k</code>. A sequence of integers <code>seq</code> is called <strong>good</strong> if there are <strong>at most</strong> <code>k</code> indices <code>i</code> in the range <code>[0, seq.length - 2]</code> such that <code>seq[i] != seq[i + 1]</code>.</p>
|
|
|
|
<p>Return the <strong>maximum</strong> possible length of a <strong>good</strong> <span data-keyword="subsequence-array">subsequence</span> of <code>nums</code>.</p>
