Lowest Common Ancestor (LCA) of binary tree in java

WebThe node with value = 35 has children with values 2 and 3 so their sum i.s 2 + 3 = 5 < 35. As we can't decrement any value, so instead we have to increase the sum of children and thus we update 35's children (2 and 3) as 30 and 5 so that 30 + 5 = 35 and the same is done for the children of the node with value = 10. The final tree looks like this : WebExplanation: The LCA of nodes 2 and 4 is 2, since a node can be a descendant of itself according to the LCA definition.
