Using java 7:

import java.math.BigDecimal; import java.util.*; class Solution{

public static void main(String []args){
    //Input
    Scanner sc= new Scanner(System.in);
    int n=sc.nextInt();
    String []s=new String[n+2];
    for(int i=0;i<n;i++){
        s[i]=sc.next();
    }
    sc.close();

    //Write your code here
    Arrays.sort(s, 0, n, new Comparator<String>() {
    @Override
    public int compare(String a, String b) {
        BigDecimal anum = new BigDecimal(a);
        BigDecimal bnum = new BigDecimal(b);
        return bnum.compareTo(anum);
    }
});

    //Output
    for(int i=0;i<n;i++)
    {
        System.out.println(s[i]);
    }
}

}
