joinList(n) (2 pts) Takes an integer number n. This functions returns the list [1,2,..,n,n,...2,1] for every n>0. Preconditions: While the function will receive integer values, you should not make any assumptions about the value of n. Input An integer value Output list Starting at 1 moving upwards, a list with the sequence 1 to n, followed the sequence that starts at n moving downwards to 1 Argument do not satisfy the conditions of the function None Example: >>> joinList(5) [1, 2, 3, 4, 5, 5, 4, 3, 2, 1] >>> joinList(1) [1, 1] >>> joinList(-3) is None True

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.

• find_last(my_list, x): Takes two inputs: the first being a list and the second being any type. Returns the index of the last element of the list which is equal to the second input; if it cannot be found, returns None instead. >> find_last(['a', 'b', 'b', 'a'], 'b') 2 >>> ind = find_last(['a', 'b', 'b', 'a'], 'c') >>> print(ind) None
3- Write a program that randomly generates 10 numbers (between 1 and 8), inserts into queue and then finds how many distinct elements exist in the queue. Example 1: Example 2: Queue: 2 40 3 3 2 18 4 18 18 3 Queue: 1 1 4 33 16 16 4 16 4 Output: 5 Output: 4 Notes: • You must use ONLY queue data structure. Don't use other different data structures like string or normal (pure) array or stack or array list. • Don't write any other method in the Qeueu class. All methods must be written in the main program.
Circular linked list is a form of the linked list data structure where all nodes are connected as in a circle, which means there is no NULL at the end. Circular lists are generally used in applications which needs to go around the list repeatedly. struct Node * insertTONull (struct Node *last, int data) // This function is only for empty list 11 5 15 struct Node insertStart (struct Node +last, int data) In this question, you are going to implement the insert functions of a circular linked list in C. The Node struct, print function and the main function with its output is given below: struct Node { int data; struct Node *next; }; struct Node insertEnd (struct Node *last, int data) void print(struct Node *tailNode) struct Node *p; if (tailNode -- NULL) struct Node * insertSubseq (struct Node *last, int data, int item) puts("Empty"); return; p - tailNode → next; do{ printf("%d ",p→data); p - p > next; while(p !- tailNode →next); void main(void) { struct Node *tailNode - NULL; tailNode -…
Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…
Write a function called myunion that will take two lists x and y, and return a list that has the elements of x, followed by the elements of y that are not found in x. For example: (myunion ’(1 3 5 7 9) ’(1 2 3 4 5 6 7)) should return (1 3 5 7 9 2 4 6).

LAB: Playlist (output linked list) Given main(), complete the SongNode class to include the function PrintSongInfo(). Then write the PrintPlaylist() function in main.cpp to print all songs in the playlist. DO NOT print the head node, which does not contain user-input values. Ex: If the input is: Stomp! 380 The Brothers Johnson The Dude 337 Quincy Jones You Don't Own Me 151 Lesley Gore -1 the output is: LIST OF SONGS ------------- Title: Stomp! Length: 380 Artist: The Brothers Johnson Title: The Dude Length: 337 Artist: Quincy Jones Title: You Don't Own Me Length: 151 Artist: Lesley Gore
