        }
        else if(addr < trip_end)
        {
            long temp_addr = addr - doub_end;
            long b = temp_addr/(256 * 256 * block_size);
            System.out.println("Double Indirect Block number " + b);
            temp_addr = temp_addr - (doub_size * b);
            b = temp_addr/(256 * block_size);
            System.out.println("Single Indirect Block number " + b);

            System.out.println("Direct Block number " + b);
            long byt = temp_addr - (b * block_size);
            System.out.println("Byte number " + byt);
        }
    }
    
}

output:-

Please enter the Block Size in KB: 
1
Please enter the address: 
350000
Single Indirect Block number 0
Direct Block number 75
Byte number 816
