A file contains the $26$ characters $"$a$"$ through $"$z$".$ The file is open with the OFT index $3.$ The block size is $16$ bytes. The following operations are issued:

$1.$ read $3,$ m$,1$

$2.$ read $3,$ m$,24$

$3.$ read $3,$ m$,1$

$1)$ After operation $1,$ the first byte of the memory area m contains the character$\_\_\_\_\_\_\_.$

$2)$ After operation $1,$ the file length recorded in the OFT is $\_\_\_\_\_\_\_\_\_.$

$3)$ After operation $2,$ the current position in the OFT is $\_\_\_\_\_\_\_\_\_.$

$4)$ After operation $2,$ the r$/$w buffer in the OFT contains a copy of block number $\_\_\_\_\_\_\_\_.$

$5)$ After operation $3,$ the first byte of the memory area m will contain the character$\_\_\_\_\_\_\_\_.$ FILL IN THE BLANKS
