2829. Determine the Minimum Sum of a k-avoiding Array

Leetcode Solutions

Greedy Approach with Set

  1. Initialize an empty set selected_numbers to keep track of the integers that have been added to the k-avoiding array.
  2. Initialize sum to 0 to keep track of the sum of the k-avoiding array.
  3. Iterate from 1 to n, and for each integer i, do the following: a. Check if the set contains the complement of i with respect to k (i.e., k - i). b. If the complement is not in the set, add i to the set and to the sum. c. If the complement is in the set, skip i and check the next integer.
  4. Continue the process until the set contains n distinct integers.
  5. Return the sum as the minimum possible sum of the k-avoiding array.
