    674 - Longest Continuous Increasing Subsequence.

    Easy

    Given an unsorted array of integers nums, return the length of the longest continuous increasing subsequence (i.e. subarray). The subsequence must be strictly increasing.

    A continuous increasing subsequence is defined by two indices l and r (l < r) such that it is [nums[l], nums[l + 1], ..., nums[r - 1], nums[r]] and for each l <= i < r, nums[i] < nums[i + 1].

    Example 1:

    Input: nums = [1,3,5,4,7]

    Output: 3

    Explanation: The longest continuous increasing subsequence is [1,3,5] with length 3. Even though [1,3,5,7] is an increasing subsequence, it is not continuous as elements 5 and 7 are separated by element 4.

    Example 2:

    Input: nums = [2,2,2,2,2]

    Output: 1

    Explanation: The longest continuous increasing subsequence is [2] with length 1. Note that it must be strictly increasing.

    Constraints:

    • 1 <= nums.length <= 104
    • -109 <= nums[i] <= 109
