This assignment requires you to create a dictionary by reading the text file. Text file name: LightningP Text file contents: Stamkos3538Maroon2933Point5055Kucherov5565Killorn3340 The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. Printing the stats for each player is the most challenging part of this program. The required output should be the same well-formatted table as below: PLAYER COLUMN: 10 characters wide and left-aligned. GOALS COLUMN: 6 characters wide and centered. ASSISTS COLUMN: 8 characters wide and centered. TOTAL COLUMN: 6 characters wide and centered. Example output:

you will create a spell checker. The program will take three command line arguments: number of words in the dictionary, a dictionary file name, and a text file name. The program will first create a hash table. The number buckets of the hash table should be about twice the number of words in the dictionary. Then, it will read the dictionary from the file, insert the words into the hash table, and report collision statistics. After reading the dictionary, the spelling checker will read a list of words from a text file. Each word will be looked up in the dictionary. If it is incorrect, it will be written to the standard output together with a list of suggested corrections. The algorithm for generating corrections is given below. Hash Table The hash table programs, QuadraticProbing.h and QuadraticProbing.cpp, are posted on Canvas. The programs use quadratic probing to deal with collisions. You should carefully study these programs and make some changes to collect the required statistics.…

For this assignment I want you to create a linked list that can store generics. This work NEED JAVA FILE, it is one java program. You will need to complete the following files: insertEnd - This method is like insertFront except the item goes at the end of the list, not the beginning removeLast - This method is like the remove method, except it removes that last occurrence of the item removeAll - This method remove all items that match the provided item previous - The method returns the node in front of the item findAndMoveToFront - The method returns the first node containing the item, but as a side effect it also moves that node to the first of the list. This potentially makes future searches faster. This is called the move to front search heuristic.

msleep**** For this assignment, you must name your R file msleep.R (using Rstudio) For all questions you should load tidyverse. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) The actual data set is called msleep Round all float/dbl values to two decimal places. If your rounding does not work the way you expect, convert the tibble to a dataframe by using as.data.frame() All statistics should be run with variables in the order I state E.g., “Run a regression predicting mileage from mpg, make, and type” would be: lm(mileage ~ mpg + make + type...) Before attempting to answer these, or if you lose points upon an attempt, please review all CodeGrade information provided in the CodeGrade overview submodule - if you do not you are likely to lose points. What is the variance in total sleep for carni vores and those whose conservation status is lc? Your answer should be in a 1 X 1 data frame with a value…
