Leetcode Solutions

Finding the Smallest Non-Expressible Positive Integer

  1. Initialize an empty set to store unique elements from nums.
  2. Iterate through each element in nums and add it to the set.
  3. Start with the smallest power of 2 (i.e., 1) and check if it is in the set.
  4. If it is not in the set, return this number as it is the smallest non-expressible integer.
  5. If it is in the set, shift left to the next power of 2 and repeat step 3.
  6. Continue this process until the smallest non-expressible integer is found.
