using python I need to write a function that returns the height of a binary tree (t) using iteration. Starting Code: def height_loop(t): h = 0 return h

Code you provide code in python?

Using c++ Contact list: Binary Search A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe...

In python We have a list (named data) of numbers sorted in ascending order, for example: data = [2, 4, 5, 9, 10, 12, 13, 17, 18, 20] Write a function (named DataVar(data)), which take a list (data) as input parameter and performs the following steps on the list: 1) it finds the mean m of the data (for the given example, it is m = (2 + 4 + 5 + 9 + 10 + 12 + 13 + 17 + 18 + 20)/10 =110/10 = 11). 2) then, it finds the difference of data and m. Essentially, it finds for all data: Diff = data-m For the given example, Diff = [-9, -7, -6, -2, -1, 1, 2, 6, 7, 9]. 3) then, it finds the sum of Diff and 7. Essentially, it finds for all data: Sums = Diff+7 For the given example, Sums = [-2, 0, 1, 5, 6, 8, 9, 13, 14, 16]. 4) then, it finds the square of all the elements of Sums, such that Squares = square of the elements of Sums. For the given example, Squares = [4, 0, 1, 25, 36, 64, 81, 169, 196, 256]. 5) it finds the average of Squares and stores it in result, and returns it. For the given...

Python data structures: write a function that takes in a list (L) as input, and returns the number of inversions. An inversion in L is a pair of elements x and y such that x appears before y in L, but x > y. Your function must run in -place and implement the best possible algoritm of time complexity. def inversions(L: List) -> int:'''finds and returns number of inversions'''
