You have a huge text file with words in it. Find the smallest distance (in terms of number of words) between any two words in the file. Can you optimise your solution if the procedure will be performed several times for the same file (but different pairs of words)?
Step by step
Solved in 2 steps
- Using a csv file attached (https://file.io/NMvbdnv4E3r0), Create a program on python that use the csv file. The program should accept a user's input of a compound. It should output the molar mass (in 2 decimal places only) of the compound.by using the csv file to compute for the atomic mass at name of the elements. Furthermore, if the "elements involved" are wrong an invallid message should be outputted and only existing chemical symbols are the output. The same goes for wrong input of the "number of atoms" wherein a wrong an invallid message should be outputted and only integers are to be inputted by the user. Program should look like this: Enter compound: C6H12O6 Enter elements involved: C,H,O Enter no. of Carbon atoms: AA Enter no. of Hydrogen atoms: 12 Enter no. of Oxygen atoms: 6 Wrong input of number of atoms! Try again. or Enter compound: C6H12O6 Enter elements involved: C,H,O Enter no. of Carbon atoms: 6 Enter no. of Hydrogen atoms: 12 Enter no. of Oxygen atoms: 6…Your aim is to determine the largest k numbers among n numbers stored in a text file with one number per line.(n >> k). However, we can only read n numbers from the file line by line, ie one by one, we do not have the possibility to read and store them all at once. Under these circumstances, implement the algorithm, which finds and returns k numbers with the largest value for a given value of k out of n numbers in the file, in a programming language of your choice. Your algorithm's timecomplexity should be better than O (nk).I am trying to read in a text file called "lines.txt" that holds an entire dictionary of words with multiple words on each line. I am supposed to find the longest word in the file and the line number it is on. So far I know that I am supposed to have a line counter when initializing the first get line() to 1 but I am confused on how to parse through it.
- Write a program that reads the strings from file SortedStrings. txt and report whether the strings in the files are stored in ascending order. If the strings are not sorted in the file, display the first two strings that are out of order.The task is to implement part of a linter program using python. Specifically, you must be able to scan for grouping symbols ( "()", "[]", "{}") and ensure that there are no hanging open symbols or stray closing symbols in the source file. There will be files you will need to scan so you need the open() in your code. Also, you can use the read() or readlines() to know which lines has no opening or stray closing symbols. Example: You scan this code from a file, and you notice that there is a stray closing symbol ")". 1 int main(void) { . 123 2 3 4 printf("Hello world")); return 0; } The implementation must involve recursion in terms of scanning for the scope. If a different closing symbol is encountered or the end of file is reached, the error message "Line : missing closing symbol for "" should be displayed. For stray closing tags, the message "Line : stray closing symbol for "". Do not use "stack" in your code.You are a cyber investigator, your task is to write a python program that can read file signatures from a file and save them into a list. Each file signature is an element of your list. Then, try to find out if there is a JPG file in there. If there is a JPG file, print out a True on screen. (File Signature for JPG file is: FF D8 FF DB) The input file is: FSCS360_Midterm_Exam_Part2.txt
- I am making a program with a CSV file with three columns: names, cities, and heights. In each city, I found the average height. I need to find the two people closest to the average. Most of the time, it works, but there is an error. A person second closest to the average doesn't even appear on the list. Also, the value for their height is way too high. What changes do I need to make? import csvdata = []with open("C:\\Users\\lucas\\Downloads\\sample-data.csv") as f: reader = csv.reader(f) for row in csv.reader(f): data.append(list(row)) f.close()data.pop(0) city_list = []for i in range(len(data)): city_list.append(data[i][1])city_list.sort()unique_cities = []people_count = []for city in city_list: # this if statement analyzes which cities are in unique_cities. If they are not in the list, # then they will be appended into the list if city not in unique_cities: unique_cities.append(city)for city in unique_cities: count = city_list.count(city)…In this exercise you will design and implement a simple encryption program that can either encrypt or decrypt a string of text by following the steps below. Create a dictionary dict that maps each (lower case) character of the basic Latin alphabet to another. Make sure no one letter is mapped to itself. Do not use a simple ordering, such as reversing the alphabet. This will act as your cipher. Your program should be able to ask user for a text and encrypt it. Your program will take each character in the string and swap it with the corresponding character from the cipher, print the encrypted text. Your program should be able to decrypt encrypted text as well. It should perform the opposite operation as the encrypt does. Print the decrypted text. Create a loop that asks if the user would like to encrypt some text, decrypt some cipher text, or exit the program. Perform the operation the user selects, printing the computed text if applicable.Write a complete program that prints out the list of files in the current directory, along with their file sizes and last modified datetime stamps. Any sub-directories are ignored. At the end, print the total file size. It accepts two optional command-line arguments: Sort field (single sort key only) “name" for filename, "size" for file size, 1 "date" for last modified datetime stamp, default is “name". "asc" for ascending, "desc" for descending, 2 Sort order default is “asc". A sample execution of the program with both command line arguments provided is shown below. $ python q3a.py date desc Filename Size Last Modified fileSorter.py / 1461 / Sat Jan 30 01:40:48 2021 optimized_fib.py / 273 / Fri Jan 29 10:53:45 2021 tic-tac-toe-bot-master.zip / 37180 / Thu Jan 28 15:12:03 2021 tictactoe.py / 8157 / Thu Jan 28 14:59:45 2021 getComputerMove.py / 1131 / Thu Jan 28 14:55:22 2021 Total file size: 48203 Research how you access the file system using the functions in the os module.

- Write a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera. You may use the following table to help you, it contains the most common letters used in the English language in descending order. E A R I O T N S L C U D P M H G B F Y W K V X Z J Q 0 5 3 2 4 6 8 1 9 7 Using the following key to convert plaintext to coded text: Plaintext = Now is the time for all good men to come to the aid of their country.

She has left a secret message, of unknown length, encoded in a file for you to unravel. The setup is simple: each line of the file contains one char and one non-negative integer. The key to reading the message is organizing the characters in the proper order. The integer indicates the position of the character within the message. For example: e 2 b 1 a 3 h 5 c 4 spells 'beach' when unraveled. Write a program that will: Ask the user for the name of a file Check to see that the file exists and contains some data. Open and read this file exactly once Using your MessageDecoder class, unravel and display the message Offer to do it again on another file Required classes: You will create and submit 2 classes: MessageDecoder class: Responsible for converting a scrambled message file into plain text.
