| 4 | +<p>A <strong>subarray</strong> is called <strong>balanced</strong> if the number of <strong>distinct even</strong> numbers in the subarray is equal to the number of <strong>distinct odd</strong> numbers.</p> |
| 5 | + |
| 6 | +<p>Return the length of the <strong>longest</strong> balanced subarray.</p> |
| 7 | +A <strong>subarray</strong> is a contiguous <b>non-empty</b> sequence of elements within an array. |
