2892. Minimizing Array After Replacing Pairs With Their Product

Leetcode Solutions

Greedy Approach with Single Pass

  1. Initialize a variable count to 0 to keep track of the number of elements that cannot be combined.
  2. Initialize a variable last to store the last element that was either added to the count or combined with its previous element.
  3. Iterate through the array nums. a. If the current element is 0, return 1 immediately. b. If last is not None and the product of last and the current element is less than or equal to k, update last to be the product of last and the current element. c. If the product is greater than k, increment count by 1 and update last to be the current element.
  4. After the loop, return count as the minimum possible length of the array after the operations.
