Shortest Path in a Grid with Obstacles Elimination WebMar 13, 2024 · We make a binary tree using these integers, and each number may be used for any number of times. Each non-leaf node's value should be equal to the product of the values of its children. Return the number of binary trees we can make. The answer may be too large so return the answer modulo 10^9 + 7.

WebFeb 11, 2024 · LeetCode: Binary Tree Upside Down. Given a binary tree where all the right nodes are either leaf nodes with a sibling (a left node that shares the same parent node) or empty, flip it upside down and turn it into a tree where the original right nodes turned into left leaf nodes. Return the new root.
WebMay 20, 2024 · A binary tree level order traversal generally recommends a breadth first search ( BFS) approach with the use of a queue data structure. When we process a node ( curr ), we'll push the node's children onto the end of the queue in the order in which we want to traverse (in this case, left to right).
