Leetcode Solutions

Breadth First Search (BFS) to find largest values in each tree row

  1. If the root is null, return an empty list.
  2. Initialize an empty list largestValues to store the result.
  3. Initialize a queue and enqueue the root node.
  4. While the queue is not empty: a. Record the number of nodes at the current level (queue size). b. Initialize currMax to the smallest possible integer value. c. Iterate over the nodes at the current level: i. Dequeue a node from the queue. ii. Update currMax if the current node's value is greater. iii. Enqueue the node's children if they exist. d. After processing all nodes at the current level, add currMax to largestValues.
  5. Return the largestValues list.
