to see the changes which i have made
pls see this symbol after the line “—>”

import java.util.*;
public class Main {
public static void printt(int []arr,int t,String s,int ans,int in)
{
if(ans==t)
{
System.out.println(s);
return ;
}

    for(int i=in;i<arr.length;i++)   --->
    {
        ans+=arr[i];
        if(ans<=t && (i == in || arr[i] != arr[i - 1]))     --->
        printt(arr,t,s+arr[i]+" ",ans,i+1);             -->
        ans=ans-arr[i];
        
    }
}
public static void main(String args[]) {
    Scanner sc=new Scanner(System.in);
    int n,t;
    n=sc.nextInt();
    int arr[]=new int[n];
    for(int i=0;i<n;i++)
    arr[i]=sc.nextInt();
    Arrays.sort(arr);
    t=sc.nextInt();
    printt(arr,t,"",0,0);   --->
}

}
