    For anyone of you who still has confusion that why the size of n does not alter the memory space because n is an int variable and it does not matter how much big or small a number is stored in it an int variable will always take 4 bytes of space in memory. This also applies for the rest of the primitive datatypes like double variable will take 8 bytes.
