'''if a filesystem has a block size of 4096 bytes, this means that a file comprised of only one byte will 
still use 4096 bytes of storage. A file made up of 4097 bytes will use 4096*2=8192 bytes of storage. Knowing 
this, can you fill in the gaps in the calculate_storage function below, which calculates the total number of 
bytes needed to storage a file of a given size...? '''

    full_blocks = filesize // block_size
    # Use the modulo operator to check whether there's any  remainder
    partial_block_remainder = filesize % block_size
    # Depending on whether there's a remainder or not, return
    # the total number of bytes required to allocate enough blocks
    # to store your data.
