1673. Find the Most Competitive Subsequence

Leetcode Solutions

Approach: Using a Monotonic Stack

  1. Initialize an empty list stack to serve as the monotonic stack.
  2. Calculate additionalCount as the number of elements we can drop, which is len(nums) - k.
  3. Iterate over each element in nums: a. While stack is not empty and the last element of stack is greater than the current element and additionalCount is greater than 0, pop the last element from stack and decrement additionalCount. b. If the length of stack is less than k, append the current element to stack.
  4. Return the first k elements of stack as they form the most competitive subsequence.
