Leetcode Solutions

Define a helper function that takes the current node and the current value of the path from the root to this node.
If the current node is null, return 0.
Update the current path value by shifting it one bit to the left and adding the current node's value.
If the current node is a leaf, return the current path value.
Recursively call the helper function for the left and right children, adding their results together to get the total sum.
Initiate the recursion with the root node and an initial path value of 0.
