Computer Science Exercise: shape [★★★] Write a function same_shape : 'a tree -> 'b tree -> bool that determines whether two trees have the same shape, regardless of whether the values they carry at each node are the same. Hint: use a pattern match with three branches, where the expression being matched is a pair of trees. please use Ocaml for the coding
1. Draw the recursion tree generated when calling hanoi (3, 1, 3). The first parameter is numDisks, the second is the number of the fromPeg, and the last is the toPeg. Each node in the tree should include the function name and three parameters described above. hanoi (3, 1, 3) is the root node in the drawing.

Hi all, please help me with this Data Structures Code. Thank you. A co-worker emails you and said she developed a recursive version for doing search in a binary search tree. Here’s the code for the function: public boolean searchRecursive(Node current, int searchValue) { if (current == null) return false; if (current.data == searchValue) return true; else if (current.data > searchValue) return searchRecursive(current.right, searchValue); else return searchRecursive(current.left, searchValue); } She’s not sure if there is an error or not because the code does compile. You analyze the code and respond to her as follows: Draw a picture of what a binary search tree would look like after inserting values of 10, 15, 18, 13, 5, 1, and 8 in that order Next, if you believe there is no error with the code, then show her how the code executes when searching for different values using the tree you made in step…
