674. Longest Continuous Increasing Subsequence最长连续递增子数组
[抄题]:
Given an unsorted array of integers, find the length of longest continuous increasing subsequence (subarray).
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.

本题最低下限是1,因为起码有一个数也算是连续

[一句话思路]:
数组连续性的问题,用本地、全局变量+三元表达式即可
[输入量]:空: 正常情况:特大:特小:程序里处理到的特殊情况:异常情况(不合法不合理的输入):

673. Number of Longest Increasing Subsequence 一共有几个?最值、可行、个数,用dp了
[代码风格] :
class Solution {
public int findLengthOfLCIS(int[] nums) {
if (nums == null || nums.length == 0) {
return 0;
}
int max = 1, maxHere = 1;
for (int i = 1; i < nums.length; i++) {
max = Math.max(max, maxHere = (nums[i] > nums[i - 1]) ? maxHere + 1 : 1);
}
return max;
}
}
