<prompt> Andika suluhisho la tatizo lifuatalo katika Python: Una miti miwili ya binary root1 na root2. Fikiria kwamba wakati unaweka moja yao kufunika nyingine, baadhi ya nodes ya miti miwili ni overlapped wakati wengine si. Unahitaji kuchanganya miti miwili katika mti mpya binary. Sheria ya kuchanganya ni kwamba kama nodes mbili overlap, basi sum node thamani kama thamani mpya ya node kuunganishwa. Vinginevyo, node NULL haitumiwi kama node ya mti mpya. Kurudi mti kuunganishwa. Kumbuka: mchakato wa kuunganisha mizizi lazima kuanza kutoka nodes ya miti yote miwili.  <response>: Heres a Python solution:class TreeNode: def __init__self, val0, leftNone, rightNone: self.val val self.left left self.right rightdef mergeTreesroot1, root2: if not root1: return root2 if not root2: return root1 root1.val root2.val root1.left mergeTreesroot1.left, root2.left root1.right mergeTreesroot1.right, root2.right return root1Heres how the solution works:- We define a class TreeNode with a constructor that initializes a nodes value, left child, and right child.- We define a function mergeTrees that takes in two binary trees root1 and root2 as parameters.- If root1 is None, we return root2. If root2 is None, we return root1. This is because if either tree is empty, we want to return the non-empty tree as the merged tree.- We add the values of root1 and root2 together and update the value of root1. This will account for any overlap in nodes.- We recursively call mergeTrees on the left and right children of root1 and root2.- Finally, we return root1, which is the merged tree.
