Given an integer array nums and a positive integer k, return the most competitive subsequence of nums of size k.

\n\n

An array's subsequence is a resulting sequence obtained by erasing some (possibly zero) elements from the array.

\n\n

We define that a subsequence a is more competitive than a subsequence b (of the same length) if in the first position where a and b differ, subsequence a has a number less than the corresponding number in b. For example, [1,3,4] is more competitive than [1,3,5] because the first position they differ is at the final number, and 4 is less than 5.

\n

Example 1:

\n\n
\nInput: nums = [3,5,2,6], k = 2\nOutput: [2,6]\nExplanation: Among the set of every possible subsequence: {[3,5], [3,2], [3,6], [5,2], [5,6], [2,6]}, [2,6] is the most competitive.\n
\n\n

Example 2:

\n\n
\nInput: nums = [2,4,3,3,5,4,9,6], k = 4\nOutput: [2,3,3,4]\n
