Finding anagaram(s) of dictionary words

How can I take an input word (or sequence of letters) and output a word from a dictionary that contains exactly those letters? Does java has an English dictionary class (list of words) that I can use, or are there open source implementations of this? How can I optimize my code if this needs to be done repeatedly? ...

Maddening Linked List problem

This has been plaguing me for weeks. It's something really simple, I know it. Every time I print a singly linked list, it prints an address at the end of the list. #include <iostream> using namespace std; struct node { int info; node *link; }; node *before(node *head); node *after(node *head); void middle(node *head, node *ptr); v...

can someone please show me how to convert this pseudocode to python using nested loops

N=5 For(rate=0.05, rate <= 0.15, rate = rate +0.05) For(principle=1000, principle <= 1500, principle=principle + 1000) simple = principle * (1 + rate * N) #Where N is the number of years compound = principle * (1 + rate) ^ N print simple + " " + compound End For End For ...

Need to make sure value is within 0-255

This is probably really easy, but I'm lost on how to "make sure" it is in this range.. So basically we have class Color and many functions to implement from it. this function I need is: Effects: corrects a color value to be within 0-255 inclusive. If value is outside this range, adjusts to either 0 or 255, whichever is closer. This i...

How to read a string one letter at a time in python

I need to convert a string inputed by a user into morse code. The way our professor wants us to do this is to read from a morseCode.txt file, seperate the letters from the morseCode into two lists, then convert each letter to morse code (inserting a new line when there is a space). I have the beginning. What it does is reads the morseCo...

Boolean algebra simplification

I need to reduce this boolean expression to its simplest form. Its given that the simplest form contains 3 terms and 7 literals. The expression is: x'yz + w'x'z + x'y + wxy + w'y'z We tried this in class, and even out recitation teacher could not figure it out. Any help would be appreciated. ...

C++ Greatest Number Verification

Hey guys, I was assigned to create a program that creates n arrays composed by 10 random integers. The the program should sum all the integers and display the result. After, it has to verify which of the sums is the greatest and it has to display that array and the result. Im having troubles getting it done and would like to get some hel...

Proving that the distance values extracted in Dijkstra's algorithm is non-decreasing?

I'm reviewing my old algorithms notes and have come across this proof. It was from an assignment I had and I got it correct, but I feel that the proof certainly lacks. The question is to prove that the distance values taken from the priority queue in Dijkstra's algorithm is a non-decreasing sequence. My proof goes as follows: Pr...

finding "distance" between two pixel's colors.

Once more something relatively simple, but confused as to what they want. the method to find distance on cartesian coordinate system is distance=sqrt[(x2-x1)^2 + (y2-y1)^2] but how do i apply it here? //Requires: testColor to be a valid Color //Effects: returns the "distance" between the current Pixel's color and // ...

bash : recursive listing of all files problem

Run a recursive listing of all the files in /var/log and redirect standard output to a file called lsout.txt in your home directory. Complete this question WITHOUT leaving your home directory. An: ls -R /var/log/ > /home/bqiu/lsout.txt I reckon the above bash command is not correct. Because I found what it store...

How to count the number of right children in a binary tree?

How to count the number of right children in a binary tree? This means that I only want the children marked as right. Ex. (Left | Right) F(Root) G | H T U | I J The right children would be U,H,and J. What would be the algorithm to find these. ...

Convert integer to equivalent number of blank spaces.

I was wondering what the easiest way is to convert an integer to the equivalent number of blank spaces. I need it for the spaces between nodes when printing a binary search tree. I tried this int position = printNode.getPosition(); String formatter = "%1"+position+"s%2$s\n"; System.out.format(formatter, "", node.element); But ...

How do you determine using stat() whether a file is a symbolic link?

I basically have to write a clone of the UNIX ls command for a class, and I've got almost everything working. One thing I can't seem to figure out how to do is check whether a file is a symbolic link or not. From the man page for stat(), I see that there is a mode_t value defined, S_IFLNK. This is how I'm trying to check whether a file ...

C# Freq. Table with Random Values

Hello, I am trying to write a frequency program that will represent a bar diagram (in console code). The problem is i have no idea how exactly to caculate this frequency or how do i exactly then give the bars different heights according to there frequency (trough calculation). The frequency height is capped at 21. (meaning the bars go...

How to convert binary, OCT, HEX to calculate in Java?

Write an application that inputs one number consisting of FIVE digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each. For example, if the user types in the number 12345, the program should print 1 2 3 4 5 The following screen dump of result i...
