Splet26. feb. 2024 · Basically, we need to swap odd value of a node with even value of one of its descendants. The idea is to traverse the tree in a postorder fashion. Since we process in postorder, for each odd node encountered, its left and right subtrees are already balanced (sinked), we check if it’s an odd node and its left or right child has an even value.
