Given an integer array nums, return true if there exists a triple of indices (i, j, k) such that i < j < k and nums[i] < nums[j] < nums[k]. If no such indices exists, return false.

\n

Example 1:

\n\n
\nInput: nums = [1,2,3,4,5]\nOutput: true\nExplanation: Any triplet where i < j < k is valid.\n
\n\n

Example 2:

\n\n
\nInput: nums = [5,4,3,2,1]\nOutput: false\nExplanation: No triplet exists.\n
\n\n

Example 3:

\n\n
\nInput: nums = [2,1,5,0,4,6]\nOutput: true\nExplanation: The triplet (3, 4, 5) is valid because nums[3] == 0 < nums[4] == 4 < nums[5] == 6.\n
