Given an unsorted array of integers, find the length of the 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. Note: The length of the array will not exceed 10,000.
public class Solution {
public int FindLengthOfLCIS(int[] nums) {
if(nums.Length == 0){
return 0;
}
int max = 0;
int curr = 1;
for(int i=1;i<nums.Length;i++){
if(nums[i]>nums[i-1]){
curr++;
}
else{
if(max<curr){
max = curr;
}
curr=1;
}
}
if(max<curr){
max = curr;
}
return max;
}
}
