Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

EXERCISES
Exercise 1
Write a function "finalGrade" that takes a list "classList" which contains a sublist for each
student. Each sublist contains three grades; attendance, exam grade, and homework grade. You need to
return a tuple that contains the average of attendance, average of exams, and average of homeworks
for the whole class.
Sample Input
classList =
[[20,80,90],[10,60,40],[17, 77,56], [21,99,99]]
Sample Output
(17,79,71.25)
*Hints: The class has 4 students
average attendance =
(20+10+17+21)/4 = 17
average exams =
(80+60+77+99)/4 = 79
average homeworks =
(90+40+56+99)/4 = 71.25

vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 True
JS Write a function named find_value that takes a list/array of whole numbers as a parameter. Your functio will need to find if the parameter contains the value 3 as an entry. Return true if the input has an entry equivalent to 3 and false if it does not.
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} INPUT: [{p=79, b=10, g=28, h=21, z=62}, {p=5, g=87, h=38}, {p=29,…
Scrabble Scrabble is a game where players get points by spelling words. Words are scored by adding together the point values of each individual letter. Define a function scrabble_score (word:str) -> int that takes a string word as input and returns the equivalent scrabble score for that word. score = {"a": 1, "c": 3, "f": 4, "i": 1, "1": 1, "o": 1, "r": 1, "u": 1, "t": 1, "x": 8, "z": 10} For example, "b": 3, "h": 4, "n": 1, Your Answer: == 20 assert scrabble_score("quick") assert scrabble_score("code") == 7 1 # Put your answer here 2 Submit "e": 1, "d": 2, "g": 2, "k": 5, "j": 8, "m": 3, "q": 10, "p": 3, "s": 1, "w": 4, "v": 4, "y": 4,
JS Write a function named list_concat that has a single parameter. This parameter will be a list/array. The parameter's entries will be strings. Your function needs to return a string. The returned string's value should be the concatention of all of the entries in the parameter with a space after each entry. Sample test cases: list_concat(["single"]) evaluates to "single list_concat(["limit", "break", "ready"]) evaluates to "limit break ready
Exercise 1 Write a function called nested_sum that takes a list of lists of integers and adds up the elements from all of the nested lists. For example: >>> t = [[1, 2], [3], [4, 5, 6]] >>> nested_sum(t) 21
18) Write a function that takes in 2 lists and checks whether they have the same elements in the same order. If the elements are all the same, the function should return the string “same”. If any of the elements are different, the function should return the string “different”. The definition of the function should be: Def equals(a, b):
Exercise 3 Write a function called middle that takes a list and returns a new list that contains all but the first and last elements. For example: >>> t = [1, 2, 3, 4] >>> middle(t) [2, 3]
The programming language is - Python a. Write a function called daysOver that takes three arguments: a dictionary, a location (such as ‘Sydney’, ‘Adelaide’,etc) and a temperature and returns the number of days that were over the given temperature for the given location. For example, if we call the function using the line: total = daysOver(dictionaryData, ‘Adelaide’, 40) total will hold the number of days that Adelaide had a temperature greater than 40 celsius in the data. As a test, there were 54 days over 40 celsius in the data. Check that total is 54 for the example when you run your code. b. Use the daysOver function to print the number of days over 35 celsius for each of the following cities: 'Adelaide','Perth','Melbourne','Canberra','Sydney','Brisbane','Darwin' c. Which of the Australian cities has the most number of days over 35 celsius? My spreadsheet looks like this Since I cannot attach an excel file, my excel file name is "weatherAUS.csv"
Write a findSpelling Function -PHP Write a function findSpellings($word, $allWords) that takes a string and an array of dictionary words as parameters. The function should return an array of possible spellings for a misspelled $word. One way to approach this is to use the soundex() Words that have the same soundex are spelled similarly. Return an array of words from $allWords that match the soundex for $word. I have most of the code. How do I append the $sound to the $mathcing array?
