- 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…Write a function that gets a linked list of ints, and reverses it.

And return the resulting list after removing unwanted elements.Example:>>>removal(['A', 'B', 'C', 'D', 'E'])['B', 'C','E'
- Write a function with the signature below that returns the sum of the last k elements of a singly linked list that contains integers. int returnSumOfLastKNodes(Node* head, int k) Example: 10 -> 5->8->15->11->9->23 10 represents the head node, returnSumOfLastKNodes(Node* head, 4) will return 58.Write a function (Ocaml) that takes an ’a list and an int list of values and returns second list, with its integers values replaced by the values from the first vector at the position specified by the integer (indexing starts with 0). Large and negative numbers are to be skipped.Write a function merge that merges two lists into one, alternating elements from each list until the end of one of the lists has been reached, then appending the remaining elements of the other list. For example, merging the lists containing A B C and D E F G H should yield the list A D B E C F G H. c++
- Write a function letter_count that accepts a string txt and returns a list containing the number of times that each letter of the alphabet occurs within txt. The returned list should contain the number of occurences of all twenty-six letters of the Latin alphabet, counting both upper and lower-case instances. For example, the string 'Abacus' contains two instances of the letter 'a', and so the first element of the returned list would be 2Write a Python function countEvens that consumes an integer N and a nested list representing a matrix of arbitrary size (but larger than NxN). The function returns the number of even numbers in the NxN sub-matrix of the first N rows and columns. Note: You may assume the list argument passed to the function is a nested list of integers, but it may be larger than NxN!Write a Python Code for the given function and conditions: Given function: def insert(self, newElement) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.
- List of triples or a triple of lists? Write a function l3_of_3l : ’a list * ’b list * ’c list -> (’a * ’b * ’c) list = that transforms a triple of lists into lists of triples. If lengths don’t match then ignore leftover elements. examples l3_of_3l ([1;2;3],[1.;2.],[’a’;’b’;’c’;’d’]);; - : (int * float * char) list = [(1, 1., ’a’); (2, 2., ’b’)] l3_of_3l ([1.;2.],[’a’;’b’;’c’;’d’],[1;2;3]);; - : (float * char * int) list = [(1., ’a’, 1); (2., ’b’, 2)]Write a function that changes the places of the first and second nodes of a linked list. I.e. the First node will become the second node, and the second node will become the first node. THE FUNCTION WILL NOT EXCHANGE DATA, IT WILL CHANGE LINKS.Suppose a node of a linked list is defined as follows in your program: typedef struct{ int data; struct Node* link; } Node; Write the definition of a function, printOdd(), which displays all the odd numbers of a linked list. What will be the time complexity of printOdd()? Express the time complexity in terms of Big-O notation.
