WebDec 23, 2016 · 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 node. So, we set tamperedSum to true whenever we deduct the node value from the sum as: sum - root.value.
