Algorithm Error, What's Wrong ?
I have this algorithm meant to sort (manually, no Java function) an array with user input elements. But when I run it, i always get some kind of error. What is wrong ? import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner scan=new Scanner(System.in); int aux,i; int[] V=new int[101]; int n=scan.nextInt(); for(i=0;i<=n;i++) V[i]=scan.nextInt(); for(i=0;i<=n;i++){ aux=V[i]; if(V[i]>V[i+1]){ V[i]=V[i+1]; V[i+1]=aux; } } for(i=0;i<=n;i++) System.out.println(V[i]); } }

this isn't correct you are trying to sort in o(n) best sort algorithms are o(nlog)
this array is counter example:
[3 , 2 , 1]

Kerpoo, can you be more explicite please ?

it has proved u never can sort an array of n element in o(n) computation and the best is o(nlogn) , in above u are trying to sort in 3n computation!
let the minimum element is in the end of array and after sort must be at first, so with above code never can!
