$($Transition diagrams and transition tables$)$

Consider a fixed$-$decimal literal with no superfluous leading or trailing zeros $($called as xnum$).$

For examples, $0\mathrm{.}0,123\mathrm{.}01,$ and $123005\mathrm{.}0$ are legal, but $00\mathrm{.}0,001\mathrm{.}000,$ and $002345\mathrm{.}1000$ are illegal.

$($A$)(4$ points$)$ Write the regular expression for xnum.

$($B$)(3$ points$)$ Draw the transition diagram for xnum.

$($C$)(3$ points$)$ Draw the transition table for xnum.
