Note: instructions $00$ through $04$ have already executed. Your program begins with instruction $05.$

Note: the blocks in the table below that contain $"..."$ indicate a series of empty mailboxes. No instructions are needed for those.

Write an LMC program that does the following:

$1.$ Reads $3$ inputs $($one at a time$)$ and places them in mailbox $($memory$)$ locations $80,81,$ and $82,$ respectively. $($Hint: $6$ instructions$)$

$2.$ ADDS the first two numbers and SUBTRACTS the third number $($in that order$).($Hint: $3$ instructions$)$

$3.$ Stores the result of that calculation in mailbox $83$ and then writes it to the outbox. $($Hint: $2$ instructions$)$

$4.$ Halts $($enter either HLT or $000$ in $\backslash (\backslash$mathrm$\{$IN$\}$ ; $9012\backslash ))$

You may write the instructions in either mnemonic form $($ALL CAPS e$.$g$.$ STO $80)$ or code form $($e$.$g$.380).$ Fill in each blank with only the contents of the mailbox $($no notes or explanations$)$
