456 - 132 Pattern\. Medium Given an array of `n` integers `nums`, a **132 pattern** is a subsequence of three integers `nums[i]`, `nums[j]` and `nums[k]` such that `i < j < k` and `nums[i] < nums[k] < nums[j]`. Return _`true` if there is a **132 pattern** in `nums`, otherwise, return `false`._ **Example 1:** **Input:** nums = [1,2,3,4] **Output:** false **Explanation:** There is no 132 pattern in the sequence. **Example 2:** **Input:** nums = [3,1,4,2] **Output:** true **Explanation:** There is a 132 pattern in the sequence: [1, 4, 2]. **Example 3:** **Input:** nums = [-1,3,2,0] **Output:** true **Explanation:** There are three 132 patterns in the sequence: [-1, 3, 2], [-1, 3, 0] and [-1, 2, 0]. **Constraints:** * `n == nums.length` * 1 <= n <= 2 * 105 * -109 <= nums[i] <= 109
