EasyNeetCode150Array
Longest Continuous Increasing Subsequence
Find longest continuous increasing subsequence.
Examples
Input
nums = [1,3,5,4,7]
Output
3
[1,3,5] has length 3.
Constraints
- •
1 <= nums.length <= 10^4 - •
-10^9 <= nums[i] <= 10^9
Approaches
Check all subarrays.
CodeT: O(n^2) | S: O(1)
Track current length.
CodeT: O(n) | S: O(1)
Same approach.
CodeT: O(n) | S: O(1)
Complexity Comparison
| Approach | Time | Space | Description |
|---|---|---|---|
| Brute Force | O(n^2) | O(1) | Check all subarrays. |
| Single Pass | O(n) | O(1) | Track current length. |
| Single Pass Optimized | O(n) | O(1) | Same approach. |
Brute Force
T: O(n^2)S: O(1)
