Leetcode Solutions

Using a Set to Track Excavated Cells

  1. Initialize a set to store the coordinates of the excavated cells.
  2. Iterate over the dig array and add each cell's coordinates to the set.
  3. Initialize a counter to keep track of the number of fully excavated artifacts.
  4. Iterate over the artifacts array.
    • For each artifact, iterate over the range of cells it covers.
    • Check if each cell is in the set of excavated cells.
    • If any cell is not excavated, break the loop and move to the next artifact.
    • If all cells are excavated, increment the counter.
  5. Return the counter value, which represents the number of artifacts that can be extracted.
