Recommended: … WebOct 26, 2024 · In a binary tree, to do operator++. We need to know not only where we are, but also howwe got here. One way is to do that is to implement the iterator as a stack of pointers containing the pathto the current node. In essence, we would use the stack to simulate the activation stack during a recursive traversal. But that’s pretty clumsy.
