During a drought, each household in a village is restricted to a certain limit of liters of water. The current water usage of each household is tracked and stored in a list.

For example, the current usage for $5$ households could be represented in the following array:

$[3\mathrm{.}5,8\mathrm{.}5,10,0,20]$

$($the first has used $3\mathrm{.}5$ liters, the second $8\mathrm{.}5$ liters, etc.$).$

Write a method$/$function to determine the remaining amount of water each household is allowed to use and returns a new list containing these figures. If a household has already reached or exceeded the limit$,$ the they are not allowed any more water. For the example above for a limit of $10\mathrm{.}0$ liters, the method$/$function should return a list containing the following values.

$[6\mathrm{.}5,1\mathrm{.}5,0\mathrm{.}0,10\mathrm{.}0,0\mathrm{.}0]$

The $3$rd and $5$th households have met and exceeded the limit respectively and have $0$ remaining liters available.

Rainfall Map

Rainfall monitors from the Airbender tribe take regular measurements of rainfall in an area represented by a two dimensional n x m grid and store it as a $2$ dimensional array$/$list$.$ For example, consider the following $3$x$5$ map:

$[0\mathrm{.}75,0\mathrm{.}50,0\mathrm{.}00,-1\mathrm{.}00,0\mathrm{.}10]$

$[1\mathrm{.}00,0\mathrm{.}25,0\mathrm{.}125,0\mathrm{.}00,-5\mathrm{.}0]$

$[1\mathrm{.}25,0\mathrm{.}50,-1\mathrm{.}0,0\mathrm{.}10,2\mathrm{.}75]$

When data is not available a negative value is used. In this example $3$ of the data points are negative so we ignore them.

Write the a method$/$function that takes a map and returns the average rainfall. In the example above, $12$ data points are valid and sum to $7\mathrm{.}325$ for an average of $7\mathrm{.}325/12=0\mathrm{.}610$ units of rain $($the actual units are irrelevant$).$

Instructions & Unit Testing

For the Java version, we have provided a starter file with specific method signatures. We have also provided a JUnit starter file that has several test cases already written. In addition to implementing all methods as specified, you will be required to add additional test cases to the JUnit testing suite. Specifically, you need to add at least $2$ valid test cases for each method you need to implement.

For the Python version, we have provided a starter file with specific function signatures. We have also provided a unittest starter file that has several test cases already written. In addition to implementing all function as specified, you will be required to add additional test cases to the unittest testing suite. Specifically, you need to add at least $2$ valid test cases for each function you need to implement.

can you help me the code this I cant figure this out I got the starter code for this with functions
