For each problem, provide test data (as input files), MapReduce programs, and running results (screen shoots) on Hadoop. i) Write a program to read input file (an integer number per line) and remove duplicated numbers. ii) When data are transmitted from map to reduce, <key, value> will be automatically sorted in an ascending order. Write a program that can read input file (an integer number per line) and write them out in a descending order.

2.3 Activity 3: Bubble Sort For this activity, you are required to provide files called act3.cpp as well as a makefile to compile and run it. In your file, act3.cpp, should have a skeleton of a main program as per normal which you will then fill it in as per the following. The objective of this activity is to demonstrate the bubble sort algorithm for arrays. You are going to implement this as a function with the following definition:...

(C++ programming) Need help with homework. Write a program that can be used to gather statistical data about the number of hours per week college students play video games. The program should perform the following steps: 1). Read data from the input file into a dynamically allocated array. The first number in the input file, n, represents the number of students that were surveyed. First read this number then use it to dynamically allocate an array of n integers. On...

C++ programming language Write a program that asks the user for a file name. The file contains a series of scores(integers), each written on a separate line. The program should read the contents of the file into an array and then display the following content: 1) The scores in rows of 10 scores and in sorted in descending order. 2) The lowest score in the array 3) The highest score in the array 4) The total number of scores in...

UNIX is all about manipulating files and input/output streams fluidly, so it is important to get a strong grasp of how this fundamentally works at the system call level to understand higher-level system programming concepts. Every program automatically has three file descriptors opened by the shell standard input standard output standard error 1 2 One can use read and write other open file. Normally, standard input and output on the terminal are line-buffered, so, for example, the specified number of...

Using c++ Write a program that reads in a list of up to 25 first names from an input file nameData.txt and allows the user to display the name data, sort it in ascending or descending order, count the number of occurrences of a given name, or exit the program. The input file consists of a single names per line with each line terminated with an end of line (i.e. using Enter key to end the line). Your program should...

PROGRAM DESCRIPTION Implement the combined O(n) radix/bucket sort as described in class. (i.e. divide the input by radix, bucket sort (with no insertion sort step) once for each radix starting from the least significant. Make sure that your overall implementation is O(n) NPUT The input to your program will an unspecified number of entries. Each entry is a non-negative integer containing nine (zero padded) digits ( this means that the integer may have either leading or trailing zeros), one per...
