$[1$ pt$]$ Please design pseudo$-$code of an energy efficient model$-$based vacuum$-$cleaner agent as

follows:

$(1)$ The environment has three locations $($A$,$ B$,$ C as shown in Figure $4)$ and three states

$("$Clean$",$ "Dirty", "Unknown"$).$

$(2)$ The vacuum$-$cleaner has four actions "Left", "Right", "Suck", and "Idle",

$(3)$ The vacuum$-$cleaner will clean the dirt as soon as it senses that the current environment is

Dirty,

$(4)$ If the vacuum$-$cleaner senses the current environment is "Clean" or "Unknown", it will

remain Idle for one time point, and

$(5)$ The vacuum$-$cleaner will change location if it senses the current environment is "Clean"

for two consecutive time points in a row, and

$(6)$ The vacuum$-$cleaner will change location if it senses the current environment is

"Unknown" for two consecutive time points in a row.

$(7)$ When change locations, agent can only move "right" if it is at location $"$C$",$ move "left"

if it is at location $"$B$",$ and randomly decide to move "left" or "right" if it is location $"$A$"$

Summarize percept sequences and corresponding actions as a table $[0\mathrm{.}5$ pt$],$

Write the pseudo code of the agent $.$
