Oct 13, 2022 · Step-by-step **Binary Search** Algorithm: We basically ignore half of the elements just after one comparison. Compare x with the middle element. If x matches with the middle element, we return the mid index. Else If x is greater than the mid element, then x can only lie in the right half subarray after the mid element. So we recur for the right half..

Given **two binary** trees, you are asked to merge them into a new **binary** tree. When you put one of them over another, some nodes of the **two** trees overlap while the others don't. If **two** of the nodes overlap, the **sum** of the **two** nodes become the new node in the new tree (e.g. if the below tree 1's right leaf with value **2** and tree **2**'s right node 3 overlap, the new tree node in that.
