Question
Write a Python function that does the following:
Its name is sum_nums
It takes two arguments: a list of list (2D list) of integers and n an integers
It iterates through all of the numbers, and sum all of the ones whose value is less than n
It returns the sum
Test cases:
print( sum_nums([[2, 12, 2], [12, 5, 100, 9]], 10) ) # 18 print( sum_nums([[2, 12, 2], [10, 5, 10, 9]], 10) ) # 18 print( sum_nums([[2, 12, 2], [10, 5, 10, 9]], 0) ) # 0 print( sum_nums([], 10) ) # 0

- write in c++arrow_forwardPLEASE DO NOT USE BUILT IN FILES OR FUNCTIONS! Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names tobe in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and apointer to the previous student. Here is a sample visual. The head points to the beginning of the list. Thetail points to the end of the list.When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the…arrow_forwardWrite a function called remove_odd that takes a list of numbers that have both even and odd numbers mixed.# Function should remove all the odd numbers and return a compact list which only contains the even numbers.

List data_list contains the data samples read from the remaining input. For each element in data_list: If the element is greater than 25, output the element followed by ' at index ', the element's index in the list, and ' is flagged'. Otherwise, output the element followed by ' at index ', the element's index in the list, and ' is normal'.arrow_forwardUse Python when answering the question: Write a function primeFac that computes the prime factorization of anumber: it accepts a single argument, an integer greater than 1 it returns a list containing the prime factorization each number in the list is a prime number greater than 1 the product of the numbers in the list is the original number the factors are listed in non-decreasing order Output is in the attached picture:arrow_forward

Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…arrow_forwardIn python We have a list (named data) of numbers sorted in ascending order, for example: data = [2, 4, 5, 9, 10, 12, 13, 17, 18, 20] Write a function (named DataVar(data)), which take a list (data) as input parameter and performs the following steps on the list: 1) it finds the mean m of the data (for the given example, it is m = (2 + 4 + 5 + 9 + 10 + 12 + 13 + 17 + 18 + 20)/10 =110/10 = 11). 2) then, it finds the difference of data and m. Essentially, it finds for all data: Diff = data-m For the given example, Diff = [-9, -7, -6, -2, -1, 1, 2, 6, 7, 9]. 3) then, it finds the sum of Diff and 7. Essentially, it finds for all data: Sums = Diff+7 For the given example, Sums = [-2, 0, 1, 5, 6, 8, 9, 13, 14, 16]. 4) then, it finds the square of all the elements of Sums, such that Squares = square of the elements of Sums. For the given example, Squares = [4, 0, 1, 25, 36, 64, 81, 169, 196, 256]. 5) it finds the average of Squares and stores it in result, and returns it. For the given…arrow_forward

Inside the function remove all the duplicate items from the list and returns a new list and the input should be given by user. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its user input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.arrow_forward
