Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”. In this small example, we don’t achieve much of a savings (and indeed the…

Description You are provided a skeleton code in the file student_code.c. Some functions are completely implemented, and some are partially implemented. Additionally, you can add your own functions if required. Complete the program as per following details so that we can have functionality as described in the Synopsis above. All the code in single C file. REMEMBER DO NOT USE sleep(). 1. The given code reads the file's content for you and populates a dynamic array of type struct thread with information about the threads. The threads have filled in this list of threads for you. Additionally, you can check the threadCount variable to see how many threads were created using the input file. If more members are needed, you can add them. You might be able to initialise those extra members during file read if you wish to. 2. The main() already contains the code to read threads from input file. However, there is no code to initialize, execute and synchronize threads. You have to perform these…

Milestone #1 - Ask Quiz Type In a file called main.py, implement a program that asks the user for a quiz type and prints the file name for that quiz type. The program should have one input prompt: the integer value of the personality quiz number. Your program should print the welcome message and the list of the personality quizzes, ask for the test number, and then print the file name. You are required to use the provided dictionary with the personality quizzes names. The list of the personality quizzes should be printed in alphabetical order. See example below.
