leetcode刷题日记—— Longest Continuous Increasing Subsequence

Given an unsorted array of integers, find the length of longest continuous increasing subsequence.

Example 1:

Input: [1,3,5,4,7]
Output: 3
Explanation: The longest continuous increasing subsequence is [1,3,5], its length is 3. 
Even though [1,3,5,7] is also an increasing subsequence, it's not a continuous one where 5 and 7 are separated by 4. 

Example 2:

Input: [2,2,2,2,2]
Output: 1
Explanation: The longest continuous increasing subsequence is [2], its length is 1. 

Note:Length of the array will not exceed 10,000

代码如下：

class Solution {
    public int findLengthOfLCIS(int[] nums) {
            int res = 0, cnt = 0;
            for(int i = 0; i < nums.length; i++){
            if(i == 0 || nums[i-1] < nums[i]) res = Math.max(res, ++cnt);
            else cnt = 1;
        }
        return res;
    }
}
