Select the lines of code in the right order to create a Scheme function that generates a list of X copies of value Y Sample call: (val-list 5 10) ==> '(5 5 5 5 5 555 5 5) (define val-list ( v [ Select ] (lambda (Y X) (Y X) (lambda Y X) [ Select ] [ Select ] ;ending parenthesis have been omitted to help hide answer

Program in C. Create a program that calculates the volume of a cone. Use these steps as your guidance: Define a structure called cone. Provide it with two members, one for its radius and one for its height. In main, declare a structure of type cone and scan both of its members. Send the whole structure to function aaa. Calculate the volume in this function and return it to main. In main, print out the volume.

8-Define a scheme procedure that returns the total number of leaves of a tree For example, (count-leaves '((4 5 6) (3) () (1 2) )) returns 6 Then, manually trace the procedure with the given example.

2.  Write a Scheme function numofatoms that determines the number of elements in a list. For example, (numOfSymbols '((1 3) 7 (4 (5 2) ) ) should return 6.
