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:
2, equal elements. For example, the subarray [2,2] is good.3, equal elements. For example, the subarray [4,4,4] is good.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 <= 1051 <= nums[i] <= 106
