Consider the following Scheme function foo: (define (foo x) (cond ((null? x) 0) ((not (list? (car x))) (cond ((eq? x '()) (foo (car x))) (else (+ 1 (foo (cdr x)))))) (else (+ (foo (car x)) (foo (cdr x)))))) (8 pts) Explain what the function computes and how. Don’t just restate the function definition in English — explain the algorithm. Hint: not all the code in this function does something useful. (2 pts) Show the result of executing the expression (foo...

In C++, write a function that takes in as inputs two arrays, foo and bar, and their respective array sizes. The function should then output the concatenation of the two arrays as a singly linked list. You may assume that you are provided a singly linked list header file.

Part 1 Here is some code: def foo(var): var = [] var.append("hello") var.append("world") list = ["bah"] foo(list) print(list) Which Option is correct? A) ["hello","world"] is output because python passes the list by reference and the list is changed inside the function. B) ["bah"] is output because python passes the list by value so changes to the list in the function are made to a separate list than the one that is passed in. C) ["bah"] is output because python passes...

Consider the function f(x) = x 4 − 4x 2 . Determine the following: • The (x,y) coordinate pairs of the local minima and local maxima. • The (x,y) coordinate pair of the absolute minimum and absolute maximum, should they exist. If the absolute min/max is obtained at multiple points, list all of them. • The intervals of increasing and decreasing. • The intervals of concavity. That is, explain exactly where this function is convex and exactly where this function...
