2326. Spiral Matrix IV

Leetcode Solutions

Spiral Matrix Filling from Linked List

  1. Initialize an m x n matrix with all elements set to -1.
  2. Define four boundaries: top, bottom, left, and right to represent the current limits for traversal.
  3. Use a while loop to iterate until the linked list is exhausted.
    • Traverse from left to right boundary and fill the topmost row, then increment top boundary.
    • Traverse from top to bottom boundary and fill the rightmost column, then decrement right boundary.
    • Traverse from right to left boundary and fill the bottommost row, then decrement bottom boundary.
    • Traverse from bottom to top boundary and fill the leftmost column, then increment left boundary.
  4. After each traversal, check if the linked list has reached its end. If so, break the loop.
  5. Return the filled matrix.
