{

System.out.print(a[i]+" ");

}

Scanner sc=new Scanner(System.in);

System.out.println("\nEnter how many times you want to rotate array to left : ");

int no=sc.nextInt();

for(int i=0;i<no;i++)

{

    int first=a[0];

   for(int j=0;j<a.length-1;j++)

  {

a[j]=a[j+1];

  }

  a[a.length-1]=first;

}

System.out.println("Output Array : ");
