I'm able to figure out how to see where character "a" is in the string "abcd" but if I put "abcda" it only prints out 0, meaning that it counts only the first instance. I want to find the last or rightmost occurence of this string. Her...

I've got douta : in std_logic_vector (3 downto 0); doutb : in std_logic_vector (3 downto 0); c0 : in std_logic; f1 : in std_logic; f0 : in std_logic; res : out std_logic_vector (3 downto 0); Im' trying to build a simple ALU, and one of the function this ALU provide is when f1 and f0 both = 1 res = douta plus b plus c0 so ...
This is what my program should look like and I'm a bit confused on where I should use different layouts. I have a Window class which calls the Panel class and the Panel class calls the InputPanel and DisplayPanel classes. My InputPanel class calls my DetailsPanel, CrimePanel and ButtonPanel classes so they make up what is seen under th...

Hi, I'm trying to write a function in scheme that takes a list and squares every item on the list, then returns the list in the form (list x y z). However, I'm not sure how to write a code that will do that. So far, I have (define (square=list list) (cond [(empty? list) false] [else (list (sqr (first a-list))(square-list (res...
I have a question on the linear Towers of Hanoi. I implemented it in C++ but am trying to do the same using the tail recursive or iterative method. I am having trouble with my algorithm. This code snippet shows transferring blocks from the middle tower to the end tower. #include <stdlib.h> #include <stdio.h> using namespace std; //i...
I've developed and tested a C program on my PC and now I want to give an estimate of the power consumption required for the program to do a single run. I've analysised the running time of the application and of invidiual function calls within the application and I know the code size both in assembly lines, but also raw C lines. How woul...

Hi I am working on the following problem: Write a recursive function that calculates the sum of the negative numbers of the array. Pass in the array {15 , -7 , -19 , 8 , 5 , -6 , -1} from the main method . The recursive function should return the result -33 . Print out this value in the main method. This program should be named Negsum....
