Longest Continuous Increasing Subsequence

Description

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

Example:

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.

思路

找出所给数组中的最长连续递增子数组的长度。

Java:

public int findLengthOfLCIS(int[] nums) {
    if (nums.length == 0) {
        return 0;
    }
    int len = 1;
    int maxLen = 1;
    for (int i = 1; i < nums.length; i++) {
        if (nums[i] > nums[i-1]) {
            len++;
            if (len > maxLen) {
                maxLen = len;
            }
        } else {
            len = 1;
        }
    }
    return maxLen;
}
