## Programming Problem 27

**Due date: `r assignments %>% filter(assessment == "Module 14 Programming Problems") %>% pull(formatted_date)` at 9pm**

Write a Python function that does the following:

1.  Its name is `swap`
2.  It takes two arguments: a dictionary and a set
3.  It swaps the key and value for all of the keys that exist in the dictionary that also exist in the set
4.  It does not return anything

Test cases:

```{python}
#| echo: true
#| eval: false
dict_data = {'a':'b', 'c':'d', 'e':'f'}
set_data = {'c', 'e'}
swap(dict_data, set_data)
print(dict_data) # {'a': 'b', 'd': 'c', 'f': 'e'}

dict_data = {23:24, 110:120, 50:45, 70:50, 57:1}
set_data = {23, 110, 57}
swap(dict_data, set_data)
print(dict_data) # {50: 45, 70: 50, 24: 23, 120: 110, 1: 57}

dict_data = {23:24, 110:120, 50:45, 70:50, 57:1}
set_data = {100}
swap(dict_data, set_data)
print(dict_data) # {23:24, 110:120, 50:45, 70:50, 57:1}
```

Name the program `swap_structures.py`. Make sure that gradescope gives you the points for passing the test case.

## Programming Problem 28

**Due date: `r assignments %>% filter(assessment == "Module 14 Programming Problems") %>% pull(formatted_date)` at 9pm**

Write a Python function that does the following:

1.  Its name is `get_elements`
2.  It two arguments: a `dictionary` with strings as keys and integers as values, and an integer `n`
3.  It returns a list containing all of the values who fall into at **least one** of these three categories:
    -   The corresponding key starts with an upper-case letter
    -   The corresponding key ends with an upper-case letter
    -   The value is greater than or equal to the second parameter integer

Test cases:

```{python}
#| echo: true
#| eval: false
data = {'Alpha':10, 'bravo':25, 'charliE':15, 'dELTa':2}
print( get_elements(data, 12) ) # [10, 25, 15]
```

Name the program `get_specific.py`. Make sure that gradescope gives you the points for passing the test case.
