Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
The file london_weather.csv contains weather data for the years 1979 to 2020. The first five lines of this file are: date,cloud_cover,sunshine,global_radiation,max_temp,mean_temp,min_temp,precipitation,pressure,snow_depth19790101,2,7,52,2.3,-4.1,-7.5,0.4,101900,919790102,6,1.7,27,1.6,-2.6,-7.5,0,102530,819790103,5,0,13,1.3,-2.8,-7.2,0,102050,419790104,8,0,13,-0.3,-2.6,-6.5,0,100840,2 Note, in particular, that the dates are given as eight-digit integers in the format YYYYMMDD. There appears to be some inconsistencies in this data, as there are rows for which the column max_temp contains an entry that is smaller than the corresponding entry in min_temp. Write a Python function wrong_temperature(year) that returns the number of days in a given year for which the column max_temp contains an entry that is smaller than the corresponding entry in the column min_temp.
I need to merge three datasets so that I can create a custom function that would do the following: Create a function called theme_by_year that takes as input a year (as an integer) and shows the theme ids and theme names (listed in order by theme id) that were in sets that year. The column names must be id and name_themes (to differentiate between the name of a theme and the name of a set) in that order. The index should be reset and go from 0 to n-1. Each theme should only be listed once even if it appeared in more than one set from that year -- duplicate themes should be based on theme id and not name since there are some themes with the same name but with a different id. Hint: It will help if you were to think about merging appropriate DataFrames to help you get this answer. The desired output should look like this: theme_by_year(1960) Output: id name_themes0 371 Supplemental1 497 Books2 513 Classic Here's what I tried, but I did not get the desired output:

Please help me write the following function (see the photos for context of the problem): follow_trail(filename, treasure_map, start_row, start_col): Takes as inputs a string corresponding to a filename, a list of lists corresponding to a treasure map, and two non-negative integers representing a row and column index. Follows the trail in the given treasure map, starting at the given row and column index. Following the trail means to look at each character of the trail and perform the appropriate operation for that character: '>', '<', 'v', ' ∧': Continues following the trail by moving to the character to the right, left, below or above the current trail character, respectively. '.': Creates a new map file, with 'new_' prepended to the current map filename, and stores the same treasure map but with an X at the current position. Then, returns a tuple of three elements: the first being -1, and the latter two being the current row and column index. '*': Returns a tuple of three…
You are required to develop a data structure which keeps the record of the courses an ABCuniversity offers. A student shall only be enrolled in a course if its prerequisite is cleared.All the courses will have an address to its prerequisite course being offered and shall be calledits neighboring nodes. Course details should include course name and credit hours.A. Implement an insert function in a relevant data structure which store course details.Note: When a new course is inserted it must verify its previous course is a prerequisite ofthe inserted course.B. Implement a function which take user details and allocate him/her in Data structurecourse after verifying prerequisite courses.C. Implement a function in which we can check credit hours of any course.
Which of the following statement is true? 103: Group of answer choices The ++ operation on an iterator moves it to the container’s next element. Many algorithms operate on sequences of elements defined by iterators pointing to the first element of the sequence and to the last element. Using iterators where appropriate is another example of the principle of least privilege. The * (dereferencing) operator when applied to a const iterator returns a const reference to the container element, allowing the use of non-const member functions.
