I am having difficulty calculating the summation of depths [the sum of the individual depths for all children of the root] for a given BST. I have the total number of nodes for the tree, and I am trying to calculate the average depth for the tree, requiring I have this depth sum. Recursion and I don't get along very well.. I am finding ...
Back again with another rookie question. While working on a function for my homework project I found that my menu wouldn't exit when I press X, it worked just an hour ago and I haven't changed anything in main(). I commented out all the code in my functions just to be sure that nothing in a function interfered. I just can't find any prob...
Implement a method public void search (String searchString) { } to iterate through the notes ArrayList until it finds a note that contains the searchString. It should then print either the item found or the message "String not found". So far, I have: import java.util.ArrayList; import java.util.Iterator; /** * A clas...
I've completed the Graham's exercise Chapter 5.8,and my code is: (defun max-min (vec &key (start 0) (end (length vec))) (cond ((eql start (1- end)) (values (elt vec start) (elt vec (1- end)))) ((zerop end) (values nil nil)) (t (multiple-value-bind (x y) (max-min vec :start (1+ start) :end end) (let* ((maxx ...
I'm trying to implement prefix to infix in c++, that's what i've got so far. The input should be for example something like this: /7+23 And the ouput: 7/(2+3) or (7/(2+3)) But instead I get: (/) That's the code I wrote so far: void pre_to_in(stack<char> eq) { if(nowe.empty() != true) { char test; test = eq.top();...
This is what I have so far but I don't now what to do next. The question is as follows (sorry the coding is not all appearing in one box): Implement a method public void search (String searchString) { } to iterate through the notes ArrayList until it finds a note that contains the searchString. It should then print either the item fou...
I'm trying to determine for the articial neuron shown below the values (0 or 1) for the inputs i1, i2, and i3 for which it will fire (i0 is the input for the bias weight and will always be -1). The weights are W0 = 1.5 W1 = -1 W2 = 1, and W3 = 2. Assume the activation function depicted in image below. Please clarify your answer ...
I am trying to write a Prolog program that will print out the male successors of British Royalty in order. My attempt so far: son(elizabeth, charles). son(charles, william). son(charles, henry). son(elizabeth, andrew). son(elizabeth, edward). son(edward, severn). successor(X, Y) :- son(X, Y). successor(X, Y) :- son(X, C), successor(C, Y...
I have a homework assigment to iterate through an object array and print out these objects using for and foreach. I'm stuck on how to do that. Questions When you use a foreach loop, don't you have to declare the object? So the object declared in a foreach loop is null, because it doesn't call any constructors in my Employee class. Cod...
This is a dumb question and I feel embarrassed to ask it, but I'm pressed for time and I'm burnt out. I have this sambple input: 1 4 2 3 0 5 6 7 8 3 1 2 6 4 5 0 7 8 -1 -1 -1 each group of numbers represents a board of the 8 puzzle, I don't know how many boards will appear on the text file. I only know its end is marked with -1 -1 ...
What I am trying to do here is set the layout scheme once I press a button to align all the buttons to the left of the contentPane I have three buttons this is the code i have for that particular button leftButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { cp.setLayout( new FlowLayout(F...
I've heard that the 8-puzzle problem can be tackled via BFS, but I don't understand how. I wanna know the intermediate steps that I need to get from a board like this: 3 1 2 6 4 5 0 7 8 to 1 2 3 4 5 6 7 8 0 Are the intermediate steps "levels" on a BFS search? By the way, this is basic homework, I don't care about optimality. ...
Hey guys, So my assignment is to create multiple classes for a Person, Name, ID #, Address, and Phone #. Name makes up: First, Middle, and Last name. ID # makes up: 9 digits. Address makes up: street, city, state, and 5 digit zip code. Phone # makes up: 3 digit area code and 7 digit number. Person makes up: a full Name (First, Middle, L...
Hello, I apologize in advance for the basic level of my question. I would like to the print the: total number and identity of nodes that have 0 child, 1 child, 2 children, 3 children. total number of node that have 0 parent, 1 parent, 2 parents, 3 parents. here is my simple script. thanks.

Greetings everyone. I am designing a digital clock in VHDL which I am supposed to synthesize on a FPGA . I am cascading S1,S2,M1,M2,H1 and H2 where (S1 = second 1, M1 = Minute 1, H1 = hour 1 etc.). One of the requirements is for the clock to switch between 24HR display to a 12HR display format. How do I do it given that H1 and H2 are r...
The question is pretty much fully embedded in the title. ...
i want to terminate the input at '=' character for example that i have given the input 2 +3= as soon as i give the '=' character it should process the input and display the output. Any help.. Spaces can also be included in the input. (it should not take any input after '=' character) the pl is c++ or c ...
Consider the following source snippets: Snippet #1 StoredProcedure sp = new StoredProcedure( "PROC_NAME", getConnection() ); sp.putParameter( "ID", getId() ); sp.execute(); Snippet #2 StoredProcedure sp = new StoredProcedure( "PROC_NAME" ); sp.setConnection( getConnection() ); sp.putParameter( "ID", getId() ); sp.execu...
How can I write a relation in prolog that determines if there are any two pairs in a list with the same sum. The relation should fail if there exist no pairs whose sums are equal. The relation should also fail if the list contains less than four elements. list([1 2 3]) fails since it only has 3 elements list([2 3 4 1]) succeeds since...
