WebNov 15, 2024 · Recursive Binary Search in Python We can also use recursion to perform a binary search. This is where we’ll define a function that keeps calling itself until a condition – our number being found – is met. Define a Recursive Function Like in our last example, we’ll start by writing a function that performs our binary search: Webclass Solution (object): def inorderTraversal (self, root): res = [] if root: res = self.inorderTraversal (root.left) res.append (root.val) res = res + self.inorderTraversal (root.right) return res In this, it returns the left branch, the value, and then the right.
