Write a statement to retrieve a cursor containing all documents where there is only one account. 2) Write a statement that returns only the email addresses of all customer documents. 3) Write a statement to retrieve a cursor containing all customer documents where the active field within the main document (i.e., do not worry about nested documents) is set to true. 4) Write a statement to retrieve a cursor containing all customer documents that do not have the active field within the main document (i.e., do not worry about nested documents). (Hint: Take a look at the Query and Projection operators in the MongoDB documentation to find an operator that helps determine whether a field exists within a document.)
- Part B - reading CSV files You will need a Python repl to solve part B. Define a Python function named cheapest_rent_per_state that has one parameter. The parameter is a string representing the name of a CSV file. The CSV file will be portion of a dataset published by the US government showing the median (middle) rent in every county in the US. Each row in the CSV file has the same format Area Name, Efficiency, 1-Bedroom, 2-Bedroom, 3-Bedroom, 4-Bedroom, State Code The data in the Area Name and State Code columns are text. The data in all of the other columns are decimal numbers. Your function will need to use the accumulator pattern to return a dictionary. The keys of that dictionary will be the state codes read in from the file (state codes are at index 6). For each key in the dictionary, it's value should be the smallest median rent for an efficiency in that state (median rents for an efficiency are at index 1). Important Hints: * You will really, really want to use the built-in csv…struct insert_into_hash_table { // Function takes a constant Book as a parameter, inserts that book indexed by // the book's ISBN into a hash table, and returns nothing. void operator()(const Book& book) { ///// /// TO-DO (8) ||||. // Write the lines of code to insert the key (book's ISBN) and value // ("book") pair into "my_hash_table". /// END-TO-DO (8) // } std::unordered_map& my_hash_table; };2) Hash Innards Homework • Unanswered Select all true statements from the below. Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V a A hash function takes a key and produces an index into the hash table. The next step in this process is often something like 'h%SIZE' so that the hash value of the key will fit within the table b (having SIZE elements, you see). Common techniques involve exclusive or of bits within the key and folding different sections of bits within the key into each other. The best hash method for character strings is to simply add up the ASCIlI values of their individual characters. Coming up with a perfect hash for a given set of keys can be a difficult and time-consuming task.
- PYTHON prov_records_per_date() takes a 2-D list (similar to the database) and an integer representing the province ID. This function returns another 2-D list, where each element of this list stores information in the following format. [ [day1, total number of patients (both icu and non-icu) in this provice reported in day1], [day2, total number of patients (both icu and non-icu) in this provice reported in day2], ... ] >>> results = prov_records_per_date(database, 35) >>> display_dict(result) >>> display_list(result) ['2022-01-31', 239] ['2022-02-05', 393] >>> results = prov_records_per_date(database, 10) >>> display_dict(result)['2022-02-02', 225] >>> results = prov_records_per_date(database, 81) >>> display_dict(result)No data in list3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]Q6.
