Python data structures: write a function that takes in a list (L) as input, and returns the number of inversions. An inversion in L is a pair of elements x and y such that x appears before y in L, but x > y. Your function must run in -place and implement the best possible algoritm of time complexity. def inversions(L: List) -> int: '''finds and returns number of inversions'''

1. a function that takes in a list (L), and creates a copy of L. note: The function should return a pointer to the first element in the new L. [iteration and recursion]. 2. a function that takes in 2 sorted linked lists, and merges them into a single sorted list. note: This must be done in-place, and it must run in O(n+m).
In Python: Write a recursive function named Multiply2 that multiples by 2 and prints each element in a given list. For example: mylist=[1,2,3,4] Multiply2(mylist) prints: 2 4 6 8 Note: the function takes only one parameter, which is the list on which the operation will be performed. It's ok if the list becomes empty after calling the function.
python assignment Matrix class Implement a matrix class (in matrix.py). a) The initializer should take a list of lists as an argument, where each outer list is a row, and each value in an inner list is a value in the corresponding row. b) Implement the __str__ method to nicely format the string representation of the matrix: one line per row, two characters per number (%2d) and a space between numbers. For example: m = Matrix([[1,0,0],[0,1,0],[0,0,1]]) print(m)> 1 0 0> 0 1 0> 0 0 1 c) Implement a method scale(factor) that returns a new matrix where each value is multiplied by scale. For example: m = Matrix([[1,2,3],[4,5,6],[7,8,9]])n = m.scale(2)print(n)> 2 4 6> 8 10 12>14 16 18print(m)> 1 2 3> 4 5 6> 7 8 9 d) Implement a method transpose() that returns a new matrix that has been transposed. Transposing flips a matrix over its diagonal: it switches rows and columns. m = Matrix([[1,2,3],[4,5,6],[7,8,9]])print(m)> 1 2 3> 4 5 6> 7 8…
Computer Science In Racket, write a recursive function called "first-index" that returns only the first index of the specified element in a list. Ex : (first-index '1 '(3 5 1 4 5 2 1)) Would return 3 The function must take 2 arguments, the item you wish to find its index and a list
Write these in SML Write these functions in ML(SML) : Write a function dup to double each element of an integer list. One function only.dup([2,3,5]) → [2,2,3,3,5,5] Write a function dups to double each char of a string. Recursion must on list not string.dups("aabc") → "aaaabbcc" Write a function mid to keep elements of an integer list between 5 and 10. One function only.mid [12,3,6,4,5,1] → [6,5]
Write a function in a racket code that takes as input a list of elements and returns a list with elements and their position after. For example, if the input to the function is (list ’a ’b ’c) then it will return (list a 1 b 2 c 3). Make sure to use recursion
(C Program) Write a recursive function called PrintLinkedList() that outputs the integer value of each node in a linked list. Function PrintLinkedList() has one parameter, the head node of a list. The main program reads the size of the linked list, followed by the values in the list. Assume the linked list has at least 1 node.
Define the function (doubleBubbleLst lst). This function should resolve to a list of sublists, where each sublist holds a single element from lst and all sublists from lst are also bubbled, so that every list and sublist has no atoms. This is the deep recursion version of bubbleLst. For example: (doubleBubbleLst '(1 2 (3 4)) ) resolves to '((1) (2) (( (3) (4) ))).
(C Language) The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
USING PYTHON Chapter 5 -Programming Project: Implement a function that takes in two sorted lists and merges them into one list, the new list must be sorted. The function MUST run in O(m+n), where m is the length of list 1 and n the length of list 2. In other words, the function cannot do more than one pass on list 1 and list 2.
Need help with SML/ML/MPL I need to write binarySearch function that recursively implements the binary search algorithm to search a sorted integer list for a specified integer and returns true if it is found, false otherwise. For example, binarySearch ([100,200,300,400,500], 200) returns true, whereas binarySearch([100,200,300,400,500], 299) returns false. Hint: Write a helper function mid that returns a tuple (index, value) representing the middle value in a list. For example, mid [10, 2, 40, 8, 22] returns (2,40) because the value 40 at index 2 is the middle value in the list. Similarly, mid [10, 20] would return (1, 20). Use mid in conjunction with slice to implement binarySearch.
Python Lee has discovered what he thinks is a clever recursive strategy for printing the elements in a sequence (string, tuple, or list). He reasons that he can get at the first element in a sequence using the 0 index, and he can obtain a sequence of the rest of the elements by slicing from index 1. This strategy is realized in a function that expects just the sequence as an argument. If the sequence is not empty, the first element in the sequence is printed and then a recursive call is executed. On each recursive call, the sequence argument is sliced using the range 1:. Here is Lee’s function definition: def printAll(seq): if seq: print(seq[0]) printAll(seq[1:]) Write a program that tests this function and add code to trace the argument on each call. Does this function work as expected? If so, are there any hidden costs in running it? its supposed to print something like this
