- Create a file called toArray.js that reads n strings from the command line, adds them to an array, and returns them in order that they were entered. You must use a forEach loop for this file. The output will contain the size of the array and the array itself.arrow_forwardThis question is for Java, and in the picture provided.arrow_forwardWrite a program (call it intersection.py) that finds all gene symbols that appear both in the chr21_genes.txt file and in the HUGO_genes.txt file. These gene symbols should be printed to a file in alphabetical order (you can hard code the output file OUTPUT/intersection_output.txt) . The program should also print on the terminal how many common gene symbols were found. Use Lists or Sets to solve the problem. It is fine to use a temporary Dictionary to find the intersection of two Lists, but this can be simplified with Sets. Note: HUGO_genes.txt could have some duplicate entries.Remember to have these command line options:$ python3 intersection.py -h usage: intersection.py [-h] -i1 FILE1 -i2 FILE2 Provide two gene list (ignore header line), find intersection optional arguments: -h, --help show this help message and exit -i1 INFILE1, --infile1 INFILE1 Gene list 1 to open -i2 INFILE2, --infile2 INFILE2 Gene list 2 to open $ python3 intersection.py -i1 chr21_genes.txt -i2 HUGO_genes.txt #…arrow_forward
- def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. passarrow_forwardJava Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time.

There are several ways to do this.• Report how many lines were read from the file.• Search for either individual words or phrases (Hint: use the .contains method, it’ll work for either a word or a phrase)• Show both the line number and the line itself for each line that contains the search target entered by the user (you may count the first line in the file as line 0).• If a search word is part of a larger…arrow_forward
- 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...)

- In pythonarrow_forwardWrite a python program that stores current grades in a dictionary, with course codes as keys and percent grades as values. Start with an empty dictionary and then use a while loop to enable input of course codes and percent grades from the keyboard. Enter data for at least five courses. After entering the data, use a for loop and the keys to show the current status of all courses. This same loop should include code that enables determination of the worst course and the average of all courses. Both of these findings should be printed when the loop ends. The worst course should be dropped and reported. This being done, the program should use another loop and the items method to display the revised courses and grades and report the revised term average.arrow_forwardProject Details: Your program should read in a random word from a file called words.txt (note the lack of capitalization) that you provide. The file should contain one word per line. To read a random word you can generate a random number between 1 and the number of lines, and skip n-1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times. Display the scrambled word with character indexes on top. Offer the user a menu with the following choices: • Enter 1 to swap a pair of letters If this option is selected prompt the user to enter two indexes and swap the letters. Print an error message if the indexes are invalid. If the word is unscrambled successfully print a congratulatory message containing the word and the number of steps it took to unscramble. Otherwise display the new word, and offer the menu again. • Enter 2 to solve If this option is selected print the unscrambled word and quit. • Enter 3 to quit If this option is…arrow_forward
