5. Implement the function first(1) that takes one parameter. The parameter is intended to be a list of lists. The function returns one list that contains all the elements in the lists. If the list entered by the user is empty, the list returned should be []. The information below shows how you would call the function list(1) and what it would display for a typical user interaction: >>> KESTART >>> >>> help(first) Help on function first in module _ma in: first(1) first: List(1ist(..)) ==> list(..) >>> 1 = [[1,2], [3,4], [5,6,7]] >>> first(1) [1, 3, 5] >>>

this code should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.
Write in C++ Now, what if Sam wants to insert Eevee after Pikachu but he doesn't know where Pikachu is located in his list. Let's help him search for a Pokemon by its name and insert another Pokemon directly after it. Write a function secondPlace() that takes six parameters and inserts a new Pokemon into a list right after another specified pokemon. Once you find the specified Pokemon, use the insertAfter() function from the previous sub-question to add the new Pokemon. The function should return the new number of strings in the array. Note The same Pokemon may appear in the list multiple times (Sam has a bad memory). Assume that Sam wants every instance of the Pokemon he is searching for to be followed by the Pokemon he is attempting to insert. If the array is already full or if the number of strings that are going to be added to the array plus the current number of strings exceeds the total size of the array, the array should remain unchanged. Assume all inputs are lowercase…
Write a function getMultiples() that takes a list of integer numbers and an integer number as parameters, returns a new list made of the numbers in the list that are multiples of the number in the second parameter.Example: If the parameters are [44, 80, 72, 245, 7, 24] and 5, then the function will return [80, 245] which are multiples of 5 (or divisible by 5).The function must work for all integer lists and all 2nd integer parameters. pls pyhton and answer fast thank u

Write a function MedianWithoutHL(ScoreList) that takes an unsorted list of n numbers as a parameter, discards the highest and the lowest numbers and return the median. You can assume the number of items in the list is between 0.0 and 9.9. To find the median from a list of items, you have tosort the list and find out the value of the item in the middle.Note: If the list has an odd number of items, the median is the value of the middle item. If the list has an even number of items, the median is the average of the two middle items.Sample Run #1:scoreList1 = [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]print("The Original ScoreList: ", scoreList1)print(MedianWithoutHL(scoreList1))Output of Sample Run #1:The Original ScoreList: [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]The List after sorting: [5.0, 6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0, 9.5]Without the High & Low: [6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0]7.75
Use clojure, define a function called remove-second that takes a list, and returns a new list that is the same as the input list, but with the second value removed. For example, given '(3 1 4), remove-second should return the list '(3 4).
rite a function numPairs that accepts two arguments, a target number and a list of numbers. The function then returns the count of pairs of numbers from the list that sum to the target number. In the first example the answer is 2 because the pairs (0,3) and (1,2) both sum to 3. The pair can be two of the same number, e.g. (2,2) but only if the two 2’s are separate twos in the list.In the last example below, there are three 2’s, so there are three different pairs (2,2) so there are 5 pairs total that sum to 4. Sample usage: >> numPairs( 3, [0,1,2,3] )2
Write a function getOdds() that takes a list of integer numbers as parameter, returns a new list made of only the odd numbers in the list.Example: If the parameter list contains [44, 81, 7, 24], the function will return [81, 7].
Code in python Given a list, L, the function front_two creates a new list of length 2 out of the first two items in L as follows: In the new list, the second item becomes the first item, and the first item becomes the second. If L contains only one item, the first item in the new list should be the value None. If L is empty, both items in the new list should be value None. The function returns the new list. For example: Test Result L = ['a', 'b', 'c', 'd'] print(front_two(L)) ['b', 'a'] L = [] print(front_two(L)) [None, None] L = [5, 2] print(front_two(L)) [2, 5] L = [7] print(front_two(L)) [None, 7]
Help writing an emacs/lisp function Write a function that takes one parameter that is a list of numbers and returns true (t) if all the elements of the list are multiples of the first one and nil otherwise. This said, a list generated by the function make-multiples could be passed to this new function and the result should be true. On the other hand, show an example of a list that could not have been generated by the first function for which the result is still true.
(a) Write a function top_students(marks) that takes as a parameter a non-empty list of (name, mark) tuples, where name is the name of a student (a string) and mark is the student's mark for some course (an int). The function returns a list of the names of all students whose mark equals that of the top student. If there is just a single student with the maximum mark, the return value will be a list of length 1, as in the first example in the table below. The names in the return list should be in the same order as in the input parameter list. Test Result marks = [('Beatrice', 50), ('Nerly', 90), ('Uniza', 70)] print(top_students(marks)) ['Nerly'] marks = [('Beatrice', 80), ('Nerly', 75), ('Uniza', 66), ('Joshua', 80)] print(top_students(marks)) ['Beatrice', 'Joshua'] (b) Write a function char_counts(string) that takes a string as a parameter and returns a dictionary in…
Write a function that gets a linked list of ints, and reverses it. For example - on input 1 -> 2 -> 3 -> 4, after the function finishes the execution, the list becomes 4 -> 3 -> 2 -> 1 - If the list has one element, then it doesn’t change - If the list is empty, then it doesn’t change You may use the data fields in the struct and the functions provided in LL.h and LL.c. // reverses a linked list void LL_reverse(LL_t* list); Test for the Function: void test_q3() { LL_t* lst = LLcreate(); LL_add_to_tail(lst, 1); LL_add_to_tail(lst, 3); LL_add_to_tail(lst, 8); LL_add_to_tail(lst, 4); LL_add_to_tail(lst, 3); LL_reverse(lst); intcorrect[] = {3,4,8,3,1}; inti; node_t* n = lst->head; for(i=0;i<5;i++) { if (n==NULL) { printf("Q3 ERROR: node %d==NULL unexpected\n", i); return; } if (n->data != correct[i]) { printf("Q3 ERROR: node%d->data==%d, expected %d\n", i, n->data, correct[i]); return; } n = n->next; } if (n==NULL) printf("Q3 ok\n"); } Support…
