The sound pressure level $($dB$)$ for different mound nource $($W$)$ at apecific distance $($m$)$ is tabulated as below.

$\backslash$table$[[$Sound Source $($W$),$Sound Pressure Level at Specific Distance $($dB$)],[0\mathrm{.}5$ meter,$1\mathrm{.}0$ meter,$1\mathrm{.}5$ meter,$2\mathrm{.}0$ meter$],[1\mathrm{.}0,115\mathrm{.}05,109\mathrm{.}03,106\mathrm{.}02,103\mathrm{.}01],[1\mathrm{.}5,116\mathrm{.}82,110\mathrm{.}79,106\mathrm{.}99,104\mathrm{.}77],[2\mathrm{.}0,118\mathrm{.}06,112\mathrm{.}04,108\mathrm{.}45,105\mathrm{.}44]]$

Based on the table above, write a MATLAB script $($m$-$file$)$ to compute:

a$).$ Highest sound pressure level $($dB$)$ for all sound source.

b$).$ Lowest sound pressure level $($dB$)$ for all sound source.

c$).$ Display the highest sound pressure level $($dB$)$ by comparing sound source $2\mathrm{.}0W$ to $1\mathrm{.}0W.$
