  "task_description": "You are given a **0-indexed** integer array `nums`. You have to partition the array into one or more **contiguous** subarrays. We call a partition of the array **valid** if each of the obtained subarrays satisfies **one** of the following conditions: The subarray consists of **exactly** `2,` equal elements. For example, the subarray `[2,2]` is good. The subarray consists of **exactly** `3,` equal elements. For example, the subarray `[4,4,4]` is good. The subarray consists of **exactly** `3` consecutive increasing elements, that is, the difference between adjacent elements is `1`. For example, the subarray `[3,4,5]` is good, but the subarray `[1,3,5]` is not. Return `true`_ if the array has **at least** one valid partition_. Otherwise, return `false`. **Example 1:** ``` **Input:** nums = [4,4,4,5,6] **Output:** true **Explanation:** The array can be partitioned into the subarrays [4,4] and [4,5,6]. This partition is valid, so we return true. ``` **Example 2:** ``` **Input:** nums = [1,1,1,2] **Output:** false **Explanation:** There is no valid partition for this array. ``` **Constraints:** `2 <= nums.length <= 105` `1 <= nums[i] <= 106`",
