- A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txtand the contents of ParkPhotos.txt are:…arrow_forwardMust be written in Python.arrow_forwardA file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AMarrow_forward
- Java 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. You should solve this problem using a stack and a queue. You can only…arrow_forwardThe program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.arrow_forwardIn this project, you will develop algorithms that find road routes through the bridges to travel between islands. The input is a text file containing data about the given map. Each file begins with the number of rows and columns in the map considered as maximum latitudes and maximum longitudes respectively on the map. The character "X" in the file represents the water that means if a cell contains "X" then the traveler is not allowed to occupy that cell as this car is not drivable on water. The character "0" in the file represents the road connected island. That means if a cell contains "0" then the traveler is allowed to occupy that cell as this car can drive on roads. The traveler starts at the island located at latitude = 0 and longitude = 0 (i.e., (0,0)) in the upper left corner, and the goal is to drive to the island located at (MaxLattitude-1, MaxLongitudes-1) in the lower right corner. A legal move from an island is to move left, right, up, or down to an immediately adjacent…arrow_forward

Write the values n, x, and F on the screen and in a file data f.data'. Repeat the program for positive n.arrow_forwardExercise 3: A company stores payment information for their employee working on a project and paid on a project basis, in a text file whose name is entered through keyboard (see a sample input file below). The first line of the file indicates the number of employees and each subsequent line corresponds to information related to an employee payment (employee name, number of hours worked and his/her hourly wage). Write a python program that reads such a file and displays the employees' names, their hours worked, and their salaries. Finally, it displays the total payment. Your program should consider the following erroneous cases: • The file does not open/exist The format of the data in the file is incorrect (e.g. hours ="1-" or salary = "unkown") in which case a RuntimeError exception should be raised and the processing should continue Enter input filename: employees.txt Employee Hours Salary 520 Badria Al-Harthi Youcef Al-Busaidi File contents invalid.

- Pythonarrow_forwardCounting the character occurrences in a file For this task you are asked to write a program that will open a file called "story.txt" and count the number of occurrences of each letter from the alphabet in this file. At the end your program will output the following report: Number of occurrences for the alphabets: a was used – times. b was used – times. c was used – times.... .and so, on Assume the file contains only lower-case letters and for simplicity just a single paragraph. Your program should keep a counter associated with each letter of the alphabet (26 counters) [Hint: Use array] Your program should also print a histogram of characters count by adding a new function print Histogram (int counters []). This function receives the counters from the previous task and instead of printing the number of times each character was used, prints a histogram of the counters. An example histogram for three letters is shown below) [Hint: Use the extended asci character 254]: A…arrow_forwardLanguage: Java 1. The sample input will have to be in Text File (.TXT) 2. By using the first function, this program reads score and name values from a file. The program then determines the grade for each students by using the second function. Finally, the program displays the name, score, and grade information on the console. The two functions are shown in the images attached below:arrow_forward
