You must complete this in Python and the programs should not take any command-line arguments. You also need to make sure your programs will compile and run in at least a Linux environment.
In this problem, you must implement a tokenizer for the Assembly instruction format: an operation type (e.g. SUBI) followed by a comma-separated list of parameters (e.g. R0, R1, 6). If a line has an invalid syntax, it should be skipped in the output. You do not need to check whether the operations and arguments are valid Assembly instructions: you just need to separate them into tokens. Input Format The input to the program will consist of some number of lines. Each line is of the following form: "op arg1, arg2, ..., argn". Your program should terminate upon receiving a blank line or EOF. Constraints There are no specific constraints on the length or number of lines. They will be in a reasonable limit, as demonstrated by the included test cases, all of which are public. This is not a performance-centric problem. Output Format The tokenized output from each input line should be given as a series of space-separated tokens, without commas or other symbols. Invalid lines should be skipped.

The other lines have no errors, so they should be tokenized and output. The errors are as follows: TEST a, b c: the comma between b and c is missing TEST, a, b: there is an extra comma after TEST TEST, a b: the comma between a and b is missing, and there is an extra comma after TEST TEST a b: the comma between a and b is missing TEST a , b, c: there is a space before the comma between a and b TEST a, b,, c: there is an extra comma between b and c

All of the lines beginning with TEST have some sort of syntax error, so they should be omitted from the output. The other lines have no errors, so they should be tokenized and output. The errors are as follows:
- TEST a, b c: the comma between b and c is missing
- TEST, a, b: there is an extra comma after TEST
- TEST, a b: the comma between a and b is missing, and there is an extra comma after TEST
- TEST a b: the comma between a and b is missing
- TEST a , b, c: there is a space before the comma between a and b
- TEST a, b,, c: there is an extra comma between b and c

- Write a code in sim8085 for the following problem: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78, 65, 89, 56, 75arrow_forwardYou are required to write a C program on Unix/Linux in which the parent process creates three child processes, lets them run concurrently, and waits for them to return and prints their exit status. The three child processes are assigned different tasks. Child one is to calculate and display the average mark of a class of twenty students for a unit. Child one is required to get the marks from the standard input (i.e. the keyboard). Child two is to load a program called “wc” (word count) to count file1. Child two is required to get file1 by the command line argument. Child three is to modify file2 by first inserting “this is the updated version.” at the beginning of this file and then replacing all the occurrences of the word “run” by “execute” and “examine” by “study”. You are required to write your OWN program for the file update. Child three is required to get file2 by the command line argument.arrow_forwardYou are expected to use python Object-Oriented programming concepts to design and implement a system in python for building a scientific calculator which inherits its basic operations from a standard calculator. The standard calculator can perform two types of operations: an addition and a subtraction The standard calculator is capable of inputting only two integers. But the scientific calculators can also interpret decimal values. The scientific calculator is capable of four operations: addition, subtraction, cosine and sine of values. The scientific calculator can accept multiple values for the addition operation. After performing an addition, the scientific calculator will send the final result to a database.

- You must complete this in Python and the programs should not take any command-line arguments. You also need to make sure your programs will compile and run in at least a Linux environment. In this problem, you need to implement operation bit encoding for Assembly instructions. Given a line of text, your program should check whether it is a valid Assembly instruction type. If it is, your program should print out the opcode and optype of that instruction type; if the line of text is not exactly a valid Assembly instruction, your program should skip it and move to the next line of input without printing anything. Input Format The input to the program will consist of some number of lines. Each line contains some text, either a valid Assembly instruction type (with no extra whitespace or other characters, e.g. READ on a line by itself) or some other text. Constraints There are no specific constraints on the length or number of lines. They will be in a reasonable limit, as demonstrated by…arrow_forward3.
