C language. Function write the arraylist_sort function
This generic function sorts an array list using the given compare function.
l An array list
compare Pointer to the function which compares two elements
If you cannot write down a generic function which works for all types, write down a function which sorts resturants. If you cannot use function pointers, you can write down multiple functions which sort using different criteria.
Concatenate Map
This function will be given a single parameter known as the Map List. The Map List is a list of maps. Your job is to combine all the maps found in the map list into a single map and return it. There are two rules for addingvalues to the map.
You must add key-value pairs to the map in the same order they are found in the Map List. If the key already exists, it cannot be overwritten. In other words, if two or more maps have the same key, the key to be added cannot be overwritten by the subsequent maps.
Signature:
public static HashMap<String, Integer> concatenateMap(ArrayList<HashMap<String, Integer>> mapList)
Example:
INPUT: [{b=55, t=20, f=26, n=87, o=93}, {s=95, f=9, n=11, o=71}, {f=89, n=82, o=29}]OUTPUT: {b=55, s=95, t=20, f=26, n=87, o=93}
INPUT: [{v=2, f=80, z=43, k=90, n=43}, {d=41, f=98, y=39, n=83}, {d=12, v=61, y=44, n=30}]OUTPUT: {d=41, v=2, f=80, y=39, z=43, k=90, n=43}

- C++ Format Please Write a function (named "Lookup") that takes two const references to vectors. The first vector is a vector of strings. This vector is a list of words. The second parameter is a list of ints. Where each int denotes an index in the first vector. The function should return a string formed by concatenated the words (separated by a space) of the first vector in the order denoted by the second vector.

Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…arrow_forward
- Domino cycledef domino_cycle(tiles):A single domino tile is represented as a two-tuple of its pip values, such as (2,5) or (6,6). This function should determine whether the given list of tiles forms a cycle so that each tile in the list ends with the exact same pip value that its successor tile starts with, the successor of the last tile being the first tile of the list since this is supposed to be a cycle instead of a chain. Return True if the given list of domino tiles form such a cycle, and False otherwise. tiles Expected result [(3, 5), (5, 2), (2, 3)] True [(4, 4)] True [] True [(2, 6)] False [(5, 2), (2, 3), (4, 5)] False [(4, 3), (3, 1)] Falsearrow_forwardflip_matrix(mat:list)->list You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix: W R I T X H D R L G L K F M V G I S T C W N M N F Expected: W N M N F G I S T C L K F M V H D R L G W R I T X Matrix: L C S P Expected: S P L C Matrix: A D J A Q H J C I Expected: J C I A Q H A D Jarrow_forwardCLASSES, DYNAMIC ARRAYS AND POINTERS Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. in C++ Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!arrow_forward
- The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…arrow_forwardHomework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system.

The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item.

Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0. Examples: > maxCylinderVolume [(2.1, 3.4); (4.7, 2.8); (0.9, 6.1); (3.2, 5.4)];;val it : float = 194.3137888> maxCylinderVolume [(0.33, 0.66)];;val it : float = 0.2257988304arrow_forward
- Data structures find_color(colors:set, values:list) -> list The function will have two parameters. The first parameter is a set of strings known as Colors. A second parameter is a list of tuple-2 known as Values. Colors will contain a set of randomly selected colors. Values will contain a list of tuples of size 2. Each tuple will contain color (str) and a number (int). The function should look at each tuple in Values. For each tuple, add the number (the second value in the tuple) to a list of numbers if the color in the tuple (the first value in the tuple) is in Colors. In other words, find all tuples that have a color in the Colors and add the tuples numbers to a list. Finally, the function should return the list of numbers collected in the order they are found in the values list. Example: Colors: {'black', 'pink', 'yellow'} values: [('green', 100), ('yellow', 13), ('red', 6)] Expected: [13] Colors: {'yellow'} values: [('black', 54), ('pink', 5)] Expected: [] Colors: {'black',…arrow_forwardC++ Code Dynamic Arraysarrow_forwardT or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming languagearrow_forward
