Given a binary tree, find the lowest common ancestor(LCA) of two given nodes in the tree.According to the definition of LCA on Wikipedia:"The lowest common ancestor is defined between two nodesv and w as the lowest node in T that has both v and w asdescendants(where we allow a node to be a descendant of itself)."/61210187 4For example, the lowest common ancestor (LCA) of nodes 5 and 1 is 3.Another example is LCA of nodes 5 and 4 is 5,since a node can be a descendant of itself according to the LCA definition.

Question

Given a binary tree, find the lowest common ancestor
(LCA) of two given nodes in the tree.
According to the definition of LCA on Wikipedia:
"The lowest common ancestor is defined between two nodes
v and w as the lowest node in T that has both v and w as
descendants
(where we allow a node to be a descendant of itself)."

For example, the lowest common ancestor (LCA) of nodes 5 and 1 is 3.
Another example is LCA of nodes 5 and 4 is 5,
since a node can be a descendant of itself according to the LCA definition.
