input 
        23 3 4 4  42 n 23 0  9 9 n n n 3 9 9 x
        //according to input,i should create int pointer arrays. pointer arrays  
  //   starting from 1 (that is initial arrays is arrays[1].when program sees n ,it 
 //    must be jumb to arrays 2 
 //  the first int input 23 is num_arrays which used in malloc(sizeof(int)*num_arrays

   expected output
        arrays[1]   3 4 5 42
        arrays[2]   23 0 9 9
        arrays[5]   3 9 9
    another input 
      12 2 3 4 n n 2 3 4 n  12 3 x
    expected output
     arrays[1] 2 3 4
     arrays[3] 2 3 4
     arrays[4] 12 3
x is stopper
n is comman to create new pointer array
