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).

- Define a recursive function named trim; it takes as its arguments a linked list (the head node of it) and a non-negative integer representing the index of an element in the list. The function mutates the linked list such that all elements that occur after the index is removed. Additionally, the function returns a linked list of all the elements that were moved. If the index value exceeds the length of the linked list, it should raise an IndexError. For example, if we defined a list as l1 = LN(1, LN(2, LN 3))) , calling the function would return the linked list LN(2, LN(3)), and the mutated l1 would become LN(1). You must use recursion. def trim(l: LN, index: int) -> LN: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) ))).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.Implements clone which duplicates a list. Pay attention, because if there are sublists, they must be duplicated as well. Understand the implementation of the following function, which recursively displays the ids of each node in a list Develop your solution as follows: First copy the nodes of the current list (self) Create a new list with the copied nodes Loop through the nodes of the new list checking the value field If this field is also a list (use isinstance as in the show_ids function) then it calls clone on that list and substitutes the value. Complete the code: def L4(*args,**kwargs): class L4_class(L): def clone(self): def clone_node(node): return <... YOUR CODE HERE ...> r = <... YOUR CODE HERE...> return r return L4_class(*args,**kwargs)Question 1 write a curried SML function, filter, that takes two arguments, a predicate ( a function that takes a single argument and returns a bool) and a list. Calling filter f L returns a list containing only those elements of L that satisfy f (that is, only those elements that f returns true for are in the resulting list). Calling filter with an empty list returns an empty list. List members should appear in the same order in the results as in L. Do not use explicit recursion Full explain this question and text typing work only thanks
- Need help with sml languege I need to write a 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. Here is my slice function: fun count(index,hd::tl,start,stop) =if index+1 >= stop then hd::nilelse if index >= start then hd::count(index+1,tl,start,stop)else count(index+1,tl,start,stop);fun slice(x::y, start, stop) = count(0,x::y,start,stop); And here is the dummy implementation of binary…Practice recursion on lists Practice multiple base conditions Combine recursion call with and,or not operators Search for an element in a list using recursion Instructions In this lab, we will write a recursive function for searching a list of integers/strings. Write a recursive function to determine if a list contains an element. Name the function recursive_search(aList, value), where aList is a list and value if primitive type is the object we want to search for. Return a boolean, specifically True if and only if value is an element of aList else return False from the function Examples: recursive_search([1,2,3], 2) == True recursive_search([1,2,3], 4) == False recursive_search([ ], 4) == False recursive_search([ [ 1 ], 2 ], 1) == False # -----> (because the list contains [ 1 ] and 2, not 1) Hint: Think about what the base case is? When is it obvious that the element is not in the list? If we are not at the base case, how can you use the information about the first element of the…python code Write a recursive function such that, given a list of intergers (say v) and an integer value (say x), the function returns resulting subset if there is a subset of intergers in v that sum up to x. Otherwise the function returns an empty list; Also write a sample code that runs this function using an example list and value x, and state the expected result
- Suppose a node of a linked list is defined as follows in your program: typedef struct{ char data; struct Node* link; } Node; Write the definitions of two functions (i) Node* pop(Node* top) – which removes the top element of the stack, and (ii) bool compare(Node* topA, Node* topB) - which returns true if the both stacks have identical data. The function returns false if the data in both stacks are not identical. In the function definitions, top, topA, and topB point the top elements of corresponding stacks. You must use the following function definitions in your answer. The peek function has already been defined. You need to write the definition of pop and compare functions. You are not allowed to modify the parameters and/or return types of the functions. Node* pop(Node* top){ //write the function definition } char peek(Node* top){ return top->data; } bool compare(Node* topA, Node* topB){ //write the function definition } Write the time complexity in Big-O notation…Please code this in Java Or C or C++ Given two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1's digit is at the head of the list. Write a function that adds the two numbers and return the sum as linked list: Example : Input : (7-> 1 -> 6) + (5-> 9-> 2). That is 617 + 295 = 912 Output : 2-> 1 -> 9 Expected time complexity : O(m+n), where m and n are no. of nodes in first and second linked list respectively.use haskell haskell haskell haskell to write following : --> A function that is passed in a function f and a list. It should apply f to every element of your list and return the resulting list. --> A function that is passed in a list and returns the count of the smallest value of the list.
