- Write a function that returns square root if each element in list. Ex: [2,4,9,144]=========> [1.4142 , 2 , 3 , 12] WRITE IN PYTHONWrite a C function list_pass () for the linked list. This function should list all student information which average is equal or greater than 50. Use the structure shown below as the node of the linked list struct student { int stdno: char name[25]; int midterm, quiz, final: float aver; struct student *nextPtr:a- Write a Python function Salary_levels, that takes a list as an argument and returns the number of the high salaries (salary>=5000), the average salaries(1000<=salary<5000, and the low salaries (salary<1000). You can use the following list : salaries= [500,1070,1450,6500,9000,940,450,400,600,2750,1100,8400,1500,900,1200] b- Use the above function to print the counts of the high, average, and low salaries. N.B: the codes of parts a and b should be included in your answer.
- Most common names Write a function mostCommonName(L:List[str]) -> List[str] that takes a list of names (such as ["Jane", "Aaron", "Cindy", "Aaron"], and returns the most common name in this list (in this case, "Aaron"). If there is more than one such name, return a list of the most common names, in any order. That is, mostCommonName(["Jane", "Aaron", 'Jane", "Cindy", "Aaron"]) returns, for example, the list ["Aaron", "Jane" ]. If the input list is empty, return an empty list. Also, names are case- sensitive i.e. "Jane" and "JANE" are different names. assert set (mostCommonName(["Jane", "Aaron", "Jane", "Cindy", "Aaron"])) == set ( ["Ai assert set (mostCommonName(["A", "B", "C", "a", "B"])) set(["B"]) assert mostCommonName([]) == [] Your Answer: 1 # Put your answer here 2 Submit ==Write the definition of a function in Python named is_magic_square that accepts a two-dimensional list as an argument and returns either True or False to indicate whether the list is a Magic Square. (You only need the function definition, not a complete program.)Tails Function Purpose: Produce a new column-based ( e.g. dict[str, list[str]] ) table with only the first N (a parameter) rows of data for each column. * Function name: Tails Parameters: 1. dict[str, list[str]] - a column-based table of data that_will not be mutated_ 2. int - The number of "rows" to include in the resulting list * Return type: dict[str, list[str]] Implementation strategy: 1. Establish an empty dictionary that will serve as the returned dictionary this function is building up. 2. Loop through each of the columns in the first row of the table given as a parameter. 1. Inside of the loop, establish an empty list to store each of the first N values in the column. 2. Loop through the first N items of the table's column, 1. Appending each item to the previously list established in step 2.1. 3. Assign the produced list of column values to the dictionary established in step 1. 3. Return the dictionary.
- Write a function called chop_list that takes a list, modifies it by removing the first and last elements, and return a list. For example: list1=[1,2,3,4,5] -> chop_list( list1) =[2,3,4] list2=["a", "b", "e", "f") -> chop_list( list2) =["b","e"]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.If you have the following node declaration:struct Node {int number;struct Node * next;};typedef struct Node node;node *head,*newNode;Write a C program that contains the following functions to manipulate this linked list : 3. A function deletes the element in the middle of the list (free this memory location) (if the list has 100 or 101 elements, it will delete the 50th element). The function will take a list as a parameter and return the updated list. 4. 2nd function named changeFirstAndLast that swaps the node at the end of the list and the node at the beginning of the list. The function will take a list as a parameter and return the updated list. 5. 3rd function using given prototype below. This function cuts the first node of the list and adds it to the end as last node. It takes beginning address of the list as a parameter and returns the updated list.node* cutheadaddlast(node* head);
- Algorithm Efficiency 1- Programming Problem Part 1 Write a function that will have a list as an input, the task of the function is to check if all the elements in the list are unique,( i.e. no repetition of any value has occurred in the list), then the function returns true otherwise it returns false. Your program should include a main method that call the method to test it. (If you would use built-in functions in Python, use lists’ or dictionaries’ methods as we studied their time efficiency in class) 2- Algorithm AnalysisFor the function you implemented in part 1, please calculate T(n), which represents the running time of your algorithm in terms of n. Where n is the length of the list. Then find the order of magnitude of your algorithm (Big O). 3- Algorithms Comparison Please find another algorithm that solves part 1, write the code, calculate T(n) and find Big O. Then compare the efficiency with the algorithm from part1 to determine the more efficient one.nums = [9,-8,7,-6,3,2,-1,3,10,9] Use enumerate to iterate through the index and values of the nums list, and output the index where userNum is found. For example, if userNum is 3, your output should be: Number 3 found at index 4 Number 3 found at index 7PYTHON Problem Statement Given a list of numbers (nums), for each element in nums, calculate how many numbers in the list are smaller than it. Write a function that does the calculation and returns the result (as a list). For example, if you are given [6,5,4,8], your function should return [2, 1, 0, 3] because there are two numbers less than 6, one number less than 5, zero numbers less than 4, and three numbers less than 8. Sample Input smaller_than_current([6,5,4,8]) Sample Output [2, 1, 0, 3]
