task 14.1 in java Follow these steps:● Create a new java file called MyFile.java● Write code to read the content of the text file input.txt. For each line ininput.txt, write a new line in the new text file output.txt that computesthe answer to some operation on a list of numbers.● If the input.txt has the following:Min: 1,2,3,5,6Max: 1,2,3,5,6Avg: 1,2,3,5,6Your program should generate output.txt as follows:The min [1, 2, 3, 5, 6] is 1.The max of [1, 2, 3, 5, 6] is 6.The avg of [1, 2, 3, 5, 6] is 3.4.● Assume that the only operations given in the input file are min, max andavg and that a list of comma-separated integers always follows theoperation. You should define the functions min, max and avg that take ina list of integers and return the min, max or avg of the list.● Your program should handle any combination of operations and anylength of input numbers.

Python 3.7.4 Given four files named asiasales2009.txt, europesales2009.txt, africasales2009.txt, and latinamericasales2009.txt, define four file objects named asia, europe, africa, and latin, and use them, respectively, to open the four files for writing.
This question concerns the use of a book cypher to encode a message.Write a program called ‘bookcypher.py’ that accepts:1. The file name for a Project Gutenberg book text.2. A message that is to be encoded.3. A file name for output of the encoded version of the message.The program will create an encoded version of the message by replacing its words with the locationsof words in the book.Say, for example, the message is ‘meet me at the usual time and place’, and the Gutenberg text is‘The Importance of Being Earnest’ by Oscar Wilde.• There is an occurrence of ‘meet’ as the 5th word on the 493rd line of the book text.• There is an occurrence of ‘me’ as the 9th word on the 190th line of the text.• There is an occurrence of ‘at’ as the 6th word on the 8th line of the text.• And so on.Representing a word position as a conjunction of the line number and the index of the word withinthe line, we can encode the message as 493-5, 190-9, 8-6, etc.Sample I/O (user input in bold):Enter the book…

Modify the program 11-10 from pages 753-755 as follows: 1. To Length class files (Length.h and Length.cpp) add the operator overload for stream insertion (<<) and stream extraction (>>) from page 759. You should not use the modified version of class Length from page 759 because it contains more operator overloads. Instead of typing you can use copy/paste from Length1.h and Length1.cpp respectively. 2. In main() replace the lines 11-16 with appropriate usage of stream extraction overload (>>) to change "first" and "second" objects with values inputted by the end user. 3. In main(), replace the output on lines 21,22 and 25,26 with appropriate usage of stream insertion (<<) operator. The resulting output should be identical with the unmodified version of the program. 11-10: // This program demonstrates the Length class's overloaded // +, -, ==, and < operators. #include <iostream> #include "Length.h" using namespace std; int main() { Length first(0),…

C Programming Task Write a programme called pgmReduce which takes 3 arguments:1. an input file (either ASCII or binary)2. an integer factor n, and3. an output fileand reduces the input file by that factor in each dimension. For example, if the invocation is:pgmReduce inputFile 5 outputFileand inputFile is a 13x17 image, then outputFile should be a 2x3 image in which only thepixels with row and column of 0 modulo 5 in the inputFile exist
