Web23 Dec 2016 · The tamperedSum boolean is set to true when we have deducted values (of nodes) from the original sum which in this case is 8. We would invoke it as: pathSum (root, sum, false) The idea is that if the sum has been tampered i.e a node value on the path has already been deducted, we are no longer allowed to pass it as-is to the branch below the …
