Binary Tree Visualizer lets you construct a natural binary tree with given values and displays it on the screen. When removing a value, its symmetric successor is moved to the original node. All traversed nodes for the last command (insert, remove or find) are highlighted in red. Hint: You can hide the keyboard by tapping anywhere on the screen outside the buttons and text fields or by pressing the back button once. Unless specifically implemented otherwise, you can do the exact same in every other app, too.
