Minimum Depth of Binary Treeโ€“ LeetCode Problem

Problem:

Given a binary tree, find its minimum depth.

The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node.

Note: A leaf is a node with no children.

Example 1:

Input: root = [3,9,20,null,null,15,7]
Output: 2

Example 2:

Input: root = [2,null,3,null,4,null,5,null,6]
Output: 5

Constraints:

  • The number of nodes in the tree is in the range [0, 105].
  • -1000 <= Node.val <= 1000

Minimum Depth of Binary Tree Solution in C++:
class Solution {
 public:
  int minDepth(TreeNode* root) {
    if (!root)
      return 0;

    int ans = 0;
    queue<TreeNode*> q{{root}};

    while (!q.empty()) {
      ++ans;
      for (int size = q.size(); size > 0; --size) {
        TreeNode* node = q.front();
        q.pop();
        if (!node->left && !node->right)
          return ans;
        if (node->left)
          q.push(node->left);
        if (node->right)
          q.push(node->right);
      }
    }

    throw;
  }
};
Minimum Depth of Binary Tree Solution in Java:
class Solution {
  public int minDepth(TreeNode root) {
    if (root == null)
      return 0;
    if (root.left == null)
      return minDepth(root.right) + 1;
    if (root.right == null)
      return minDepth(root.left) + 1;
    return Math.min(minDepth(root.left), minDepth(root.right)) + 1;
  }
}
Minimum Depth of Binary Tree Solution in Python:
class Solution:
  def minDepth(self, root: Optional[TreeNode]) -> int:
    if not root:
      return 0
    if not root.left:
      return self.minDepth(root.right) + 1
    if not root.right:
      return self.minDepth(root.left) + 1
    return min(self.minDepth(root.left), self.minDepth(root.right)) + 1
