2 testcases not passing

#1

import java.util.*;
public class Main {
public static void main (String args[]) {

    Scanner sc= new Scanner(System.in);
    int len=sc.nextInt();
    int arr[]= new int[len];

    for(int i=0; i<len; i++){
        arr[i]=sc.nextInt();
    }

    //System.out.println(Arrays.toString(arr));

    int low=0;
    int high=0;

    while(low<len-1){
        int i=low;
        while(i!=len-1 && arr[i+1]==arr[i]+1){
            i++;
        }
        System.out.print(arr[low]+"->"+arr[i]+" ");
        low=i+1;
    }

}

}

@ANUKUL1509,

You need to print ranges like this l -> r, but if l == r then you just need to print l, just update your printing statements like this:

if(low != i){
System.out.print(arr[low]+"->"+arr[i]+" “);
}else{
System.out.print(arr[low]+” ");
}

Also, add below statement after while loop is executed,

if(low < len){
System.out.println(arr[low]);
}
