"content": "<p>You are given a <strong>0-indexed</strong> integer array <code>nums</code> and an integer <code>pivot</code>.

For elements less than <code>pivot</code>, if <code>i < j</code> and <code>nums[i] < pivot</code> and <code>nums[j] < pivot</code>, then <code>p<sub>i</sub> < p<sub>j</sub></code>.
