Problem: Increasing Triplet Subsequence

Explore how to determine if an integer array contains an increasing triplet subsequence using a linear time and constant space algorithm. Understand step-by-step how to track two key values to efficiently verify the subsequence condition, improving your problem-solving skills with Go.

Statement

Given an integer array nums, determine whether there exist three indices (i, j, k) such that i < j < k and nums[i] < nums[j] < nums[k]. Return true if such a strictly increasing triplet subsequence exists, and false otherwise.

Note: Can you implement a solution that runs in O(n) time complexity and O(1) space complexity?

Constraints:

  • 11 \leq nums.length ...
