code should do this : a) Given an unsorted array of integers, your task is to sort the array by applying the following algorithm
(Assume that the input doesn’t contain duplicates ):
Execute the following steps starting from the first element in the array:
– Count the number of smaller elements to find the correct position i.
– If the element is in its correct position, move to the succeeding element.
– Otherwise, swap the current element with the one found in position i.
– Repeat the previous steps till you reach the last element.
Example:
5 7 3 6 9
check a[0], there is one element smaller that it, so it shoould be swapped with the element at
position1.
7 5 3 6 9
check the new element a[0]. it should move to position 3.
6 5 3 7 9
check the new element a[0]. it should move to position 2.
3 5 6 7 9
check the new element a[0]. it is in its correct position, so we move to the succeeding element a[1].
public class Assignment1_T11_25_2729_Sara_Aly {
private int[] a;
private int max;
private int n;
int position=0;
public Assignment1_T11_25_2729_Sara_Aly (int max){
a= new int[max];
}
public void insert(int x){
a[n]=x;
n++;
}
public void sort(){
int out=0, smaller=0;
while(out<n){
for(int in=out+1;in<n;n++){
if(a[in]<a[out])
smaller++;
}
if (smaller==0){
out++;
}
else {
swap(a[out], a[smaller]);
}
}
}
private void swap (int one, int two){
int temp=a[one];
a[one]=a[two];
a[two]=temp;
}
public void display(){
for (int i=0;i<n;i++){
System.out.print(a[i]+ " ");
}
System.out.println("");
}
public static void main(String[]args){
int maxsize=5;
Assignment1_T11_25_2729_Sara_Aly trial;
trial= new Assignment1_T11_25_2729_Sara_Aly(maxsize);
trial.insert(5);
trial.insert(7);
trial.insert(3);
trial.insert(6);
trial.insert(9);
trial.display();
trial.sort();
trial.display();
}
}
Tried a few algorithims to get it to work but for some reason it won't sort any suggestions??
also tried this the sorting method but no luck.
public void sort(){
boolean finished = false;
int position =0;
while (position<max){
if (finished==true){
position++;
finished =false;
}
else {
int smaller=0;
for (int j = position+1; j<max; j++){
int temp=a[position];
if (a[j] <a[position]){
smaller++;
}
}
if (smaller==0){
finished= true;
}
else {
int temp= a[smaller];
a[smaller]=a[position];
a[position]=temp;
}
}
}
}
