Given an ordered list with 15 elements, how many elements must be visited in the worst case of binary search?

Consider the following recursive function: def r(xs: list[int]) -> list[int]:    match xs:        case []:            return []        case [x]:            return [x]        case [first, second, *rest]:            return [first] + r(rest) + [second] What list will r([1, 2, 3, 4]) return?

The function at_least returns True if at least two values in a list of booleans are True. Provide the Big‑O running time for the following function. def at_least( arr: list[bool] ) -> None:    count = 0    for i in range(0, len(arr)):        if arr[i] == True:            count += 1    return count >= 2

Consider the following recursive function: def p(xs: list[int]) -> list[int]:    match xs:        case []:            return []        case [x]:            return [x]        case [first, second, *rest]:            return p(rest) + [first, second] What list will p([1, 2, 3, 4, 5]) return?

Suppose you want a recursive function, product(xs: list[int]) -> int, that multiplies all the numbers it’s passed. Imagine the implementation — what do you suppose the base case for the product(..) function should return if [] is matched?

What is the worst case runtime for removing the smallest from a min heap?

Consider the selection sort function and function call shown below: note: minimumPosition(values, i) returns the index of the smallest value in the values list starting from i (inclusive) def selectionSort(values: list[int]) -> None :   for i in range(len(values)) :      print(values)      minPos = minimumPosition(values, i)      swap(values, minPos, i) data = [1, 2, 3]selectionSort(data)print(data) What is displayed when this code segment executes?

An algorithm that tests whether the first list element is equal to any of the other list elements would be an ____ algorithm.

Which of the following occupancy factors would accurately describe total occupancy (administrative or clerical offices, adjacent x-ray rooms, nurses stations, etc)?

During routine radiographic procedures, when a protective apron is not being used, occupational personnel should place the primary dosimeter at the front of the body at the collar level to approximate the location of maximal radiation dose to which of the following body parts?
