1868. Product of Two Run-Length Encoded Arrays

Leetcode Solutions

Two Pointers Approach for Run-Length Encoded Product

  1. Initialize two pointers, i and j, for encoded1 and encoded2 respectively.
  2. Initialize an empty list product_encoded to store the result.
  3. While both pointers i and j are within the bounds of their respective arrays: a. Calculate the product of the current values pointed by i and j. b. Determine the minimum frequency from the current segments. c. Subtract the minimum frequency from the frequencies of the current segments. d. If the frequency of a segment becomes zero, move the corresponding pointer forward. e. If the last segment in product_encoded has the same value as the current product, add the minimum frequency to it. f. Otherwise, append a new segment with the current product and minimum frequency to product_encoded.
  4. Return product_encoded.
