Creating Flowchart For Bubble Sort

Apr 27, 2015

I have to make a flowchart that shows a bubble sort. Here is the exact directions: provide a flowchart for a bubble sort, and write the pseudo-code that corresponds to the flowchart. You can assume the existence of a swapElement method (ie. use the predefined process symbol).one that does one pass through the array and returns a boolean if items were swapped (I'll call this the one pass method) another method that repeatedly calls the one pass method until that method returns false.This means that your flowchart will have two separate pieces for the one pass method and for the overall flow of the program (this one would use the predefined process symbol for the one pass method).

I have looked up what a bubble sort. It says it is another type of sort that involves repeatedly stepping through the array comparing adjacent items and swapping them if they are in the wrong order.The sort steps through the list multiple times until no swaps are needed, at which point the list is sorted.

Find Out Logic Behind Bubble Sort

Mar 4, 2014

I am trying to find out the logic behind the Bubble sort,

for(a=1; a < size; a++)
for(b=size-1; b >=a ; b--){
if(nums[b-1] > nums[b]){
t=nums[b-1];
nums[b-1] = nums[b];

Bubble Sort - Array Out Of Bounds Exception

Jan 10, 2015

I am having trouble with an array out of bounds exception. I understand what the error means (that I am trying to access part of array that does not exist). But I do not see the error in my code.

Java Code:

public class bubbleSort
{
public static void main(String []args)
{
int i;
int array [] = {12,9,4,99,120,1,3,10};

Linking Elements Of Two Arraylists Together For A Bubble Sort?

Jun 13, 2014

I have been doing a program that allows the user to input students names and numerical grade values. I have already completed 3/4 of the program but am stuck on the bubblesort method as this is what it requires:

The program must have an indefinite loop, which prompts the user to select a sorting criterion or to end the program, and must also use bubble sort. Note: The user may either select name or grade as the sorting criteria. The program must use bubble sort to sort that data according to the specific criteria and then use another loop to display the data. This process must continue until the user ends the program.

My problem is, while i can easily do the bubblesort, where to look on how to link elements of the two arraylists I'm using (one for grades, one for names) so that when the user decides what sort they want, the individual's name and grade stays together.

Creating Merge Sort For String Arrays

Mar 31, 2014

I'm having a problem printing out the descending order of my array. The array order goes like (Title,Studio,Year). I try to create to ints with the compareTo method but when the program is run the I get array out of bounds. Could the answer possibly be that in order not not have the out of bounds error, to create a for loop inside of the while?

public class Movie2

// instance variables

How To Sort TreeSet By Age Of Person

Aug 2, 2014

public class Person implements Comparable<Person> {
// the age of the person
private int age;
//the name of the person
private String name;
//the Integer object to wrap the age value;
private Integer ageWrap;

[Code] .....

The collection library has a class named TreeSet, which is an example of a sorted set. Elements in this set are kept in order. Carefully read the description of this class, and then write a class Person that can be inserted into a TreeSet, which will then sort the Person objects by age.

This is the exercise I am trying to solve. And this is as far as I have gotten to. Is it possible to sort my setOfPersons TreeSet directly? I tried to use

Collections.sort(setOfPersons)

method but it wont compile, and I realized that it is not applicable to TreeSet. So I made the

sortByAge()

method to do it indirectly...

I am puzzled though because in the exercise it states

write a class Person that can be inserted into a TreeSet, which will then sort the Person objects by age.

meaning that the TreeSet will sort the Person Objects and not my class..

Selection Sort Method?

Mar 5, 2014

I'm trying to make a selection sort method that will sort a list of Strings alphabetically.

I have a test list of Strings like so:

Joe, Steve, Oscar, Drew, Evan, Brian, Ryan, Adam, Zachary, Jane, Doe, Susan, Fred, Billy-Bob, Cindy, Mildred, Joseph, Hammer, Hank, Dennis, Barbara

However, whenever I run the method, the element that should go last, Zachary, in this case, ends up getting moved to the front for some reason. I'm not sure why.

I tried changing what the first element was initialized to, to the variable i as that would logically work as well, but it ends up missing the first element in the list.

Java Code:

public static void selectionStringAscendingSort (String[] words){
int i, j, first;
String temp;
for ( i = 1; i < words.length; i++ ) {
first = 0; //initialize to subscript of first element
for(j = i; j < words.length; j ++){ //locate smallest element between positions 1 and i.
if( words[ j ].compareTo(words[ first ]) <0 )
first = j;
}
temp = words[ first ]; //swap smallest found with element in position i.
words[ first ] = words[ i ];
words[ i ] = temp;
System.out.println(Arrays.toString(words));
}
System.out.println(Arrays.toString(words));
} mh_sh_highlight_all('java');

How To Use Bubblesort To Sort The Array

I wrote this piece of code, and it is supposed to use bubblesort to sort the array. Yet somehow it re-aranges it, but doesn't exactly sort it. For example, when I enter [3, 5, 6, 9, 8, 4, 7, 5, 6, 2], it prints Done [2, 5, 9, 5, 7, 8, 4, 6, 3, 6]

Sort Both Array List

Jun 29, 2014

Directions: public static void initialize(ArrayList names, ArrayList sores)

You should write a function that sorts both array lists, based on the values in the scores array list. This is one of the more conceptually challenging parts of the assignment. You want to sort the scores array list, and simultaneously alter the names array list so that the names continue to line up with their respective scores by index. In the example data above, when the score 9900 moves to the first element of the scores array list, the name "Kim" should also be moved to the top of the names array list. The function should have the following signature:

I'm having trouble figuring out how to sort the lists.

import java.util.ArrayList;
import java.util.Scanner;
public class Assignment5
{
/**
*/
public static void main(String[]args) {
intializeArrays();

Sort Two Heaps Into One Array

Dec 15, 2014

How I would sort two heaps into one array. I know that in a heap the "parent" is guaranteed to be larger than the "children".

So could I simultaneously traverse both trees in order, and while doing so, store the values of each node, one after another? This way the array would be partially sorted and then I could just use an insertion sort.

Is this logic reasonable or am I looking at it the wrong way?

Is Insertion Sort Inefficient

Jul 20, 2014

I could have copied the code for a standard algorithm such as insertion sort, but I wanted to do it on my own to see how well I think. I came up with a working solution below. This is efficient or not or if I can make improvements. Would this approach ring any alarm bells in an interview ?

public static void insertionSort(int[] unsortedArray) {
int[] a = unsortedArray;// alias for the array
int s = 0;// index before which all elements are in order.
int tmp = 0;// temporary variable
int last = a.length - 1;

Insertion Sort Pseudocode

Jan 1, 2014

I can't spot where my java implementation of insertion sort differs from the pseudocode here:Well, there is one difference in the parameters used by the insert method, which is inconsistent in the pseudocode.I'm pretty sure it should be calling insert (a,n) instead of (a,i,n);

insert(a,k) i←k
x ← a[k]
while x < a[i − 1]
x ← a[i]
a[i ] ← a[i − 1] i ←i −1
a[i]←x return

insertion-sort(a,n)
m ← select-min(a,1,n) swap(a,1,m)
fori from2upton
insert(a,i,n) return

Here is my attempt at a java implementation, which doesn't actually seem to do anything.I've kept variable names as in the pseudocode. Might technically be bad practice, butI think it should make it easier to follow in this particular scenario.public class InsertionSort {

public static void main(String[] args) {
int[] array = { 99, 2, 44, 14, 14, 44, 11, 33, 14, 14, 51 };
insertionSort(array, 10);
for (int i : array)
System.out.print(i + " ");

[code]...

Why am I so interested in this pseudocode when there are simpler java-ready examples of insertion sort on the internet? Simply because this is the code the professor uses, so I should be able to understand it.
