Implement this function

def get$\_$weather$\_$violation$($weather$,$minimums$)$:

$"""$

Returns a string representing the type of weather violation $($empty string if flight is ok$)$

The weather reading is a dictionary with the keys: 'visibility', 'wind', and $\text{'}$sky$\text{'}.$

These correspond to a visibility, wind, and ceiling measurement, respectively. It

may have other keys as well, but these can be ignored. For example, this is a possible

weather value:

$\{$

"visibility": $\{$

"prevailing": $21120\mathrm{.}0,$

"minimum": $1400\mathrm{.}0,$

"maximum": $21120\mathrm{.}0,$

"units": $"$FT$"$

$\},$

"wind": $\{$

"speed": $12\mathrm{.}0,$

"crosswind": $3\mathrm{.}0,$

"gusts": $18\mathrm{.}0,$

"units": $"$KT$"$

$\},$

"temperature": $\{$

"value": $-15\mathrm{.}6,$

"units": $"$C$"$

$\},$

$"$sky$"$: $[$

$\{$

"cover": "clouds",

"type": "broken",

"height": $2100\mathrm{.}0,$

"units": $"$FT$"$

$\}$

$],$

"weather": $[$

"light snow"

$]$

$\}$

The minimums is a list of the four minimums ceiling, visibility, and max windspeed,

and max crosswind speed in that order. Ceiling is in feet, visibility is in statute

miles, max wind and cross wind speed are both in knots. For example,

$[3000\mathrm{.}0,10\mathrm{.}0,20\mathrm{.}0,8\mathrm{.}0]$ is a potential minimums list.

This function uses bad$\_$visibility, bad$\_$winds, and bad$\_$ceiling as helpers. It returns

'Visibility' if the only problem is bad visibility, 'Winds' if the only problem is

wind, and 'Ceiling' if the only problem is the ceiling. If there are multiple

problems, it returns 'Weather', It returns 'Unknown' if no weather reading is

available $($e$.$g$.$ weather is None$).$ Finally, it returns $\text{'}\text{'}($the empty string$)$ if

the weather is fine and there are no violations.

Parameter weather: The weather measure

Precondition: weather is dictionary containing a visibility, wind, and ceiling measurement,

or None if no weather reading is available.

Parameter minimums: The safety minimums for ceiling, visibility, wind, and crosswind

Precondition: minimums is a list of four floats
