// adjust balance method func adjustBalance(rootNode *TreeNode, nodeValue int, balanceValue int) { var node *TreeNode node = rootNode.LinkedNodes[nodeValue] var oppNode *TreeNode oppNode = node.LinkedNodes[opposite(balanceValue)] switch oppNode.BalanceValue { case 0: rootNode.BalanceValue = 0 node.BalanceValue = 0 case balanceValue: rootNode.BalanceValue = -balanceValue node.BalanceValue ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
