<prompt> Kutokana na mizizi ya mti binary, kurudi jumla ya kila mti node ya tilt. tilt ya mti node ni tofauti kabisa kati ya jumla ya thamani ya wote kushoto subtree node na wote haki subtree node maadili. Kama node haina mtoto kushoto, basi jumla ya kushoto subtree node maadili ni kutibiwa kama 0. sheria ni sawa kama node haina mtoto wa kulia.  <response>: To solve this problem, you can create a recursive function that traverses the tree and calculates the tilt for each node. Here is an algorithm that you can follow:1. Initialize a variable called tiltSum to 0.2. Write a recursive function called calculateTilt that takes a node as an argument.3. In the function, check if the node is null. If it is, return 0.4. Recursively call calculateTilt for the left subtree and the right subtree of the node.5. Calculate the tilt for the current node by taking the absolute difference between the sum of the values in the left subtree and the sum of the values in the right subtree.6. Add the tilt to the tiltSum variable.7. Return the sum of the values in the left subtree, the sum of the values in the right subtree, and the value of the current node, added together.8. Call the calculateTilt function with the root node as the argument.9. Return the value of tiltSum.Here is the Python code that implements the algorithm:class TreeNode: def __init__self, val0, leftNone, rightNone: self.val val self.left left self.right rightclass Solution: def findTiltself, root: TreeNode - int: tiltSum 0 def calculateTiltnode: nonlocal tiltSum if not node: return 0 leftSum calculateTiltnode.left rightSum calculateTiltnode.right tilt absleftSum - rightSum tiltSum tilt return leftSum rightSum node.val calculateTiltroot return tiltSumNote: This code assumes that the TreeNode class has a val attribute that stores the value of the node, and left and right attributes that point to the left and right subtrees of the node.
