In JavaScript, there are two types of comments: 1. Single-line comments start with // 2. Multi-line or inline comments start with /* and end with */ The input will be a sequence of //, /* and */. Every /* must have a */ that immediately follows it. To add, there can be no single-line comments in between multi-line comments in between the /* and */ . Create a function that returns true if comments are properly formatted, and false otherwise. Examples comments Correct("//////") → true // 3 single-line comments: ["//", "//", "//"] commentsCorrect("/**//**////**/") → true // 3 multi-line comments + 1 single-line comment: // ["/*", "*/", "/*", "*/", "//", "/*", "*/"] comments Correct("///*/**/") → false // The first /* is missing a */ comments Correct("/////") → false // The 5th / is single, not a double //
with python do whis: Edit or delete a user profileWhen the user chooses 2, the first thing that it should do is to check whether the user information is loaded in the program (i.e., check if the user information is passed to the function that generates recipe recommendations). If the user information is passed to the function (i.e., the user chose option 1 before choosing option 2), the program should show the user the following menu:Hello (user name)You can perform one of the following operations:1) Delete your profile2) Edit your profilea. If the user chooses 1, perform the following subtasks to delete a user profile:1- Search for the user profile in the file userInformation.txt using the user name in read mode; once you find the user profile (i.e., the line that contains all the user information), pass it to a function that deletes the user information.2- The function should create a temporary file called temp.txt in write mode and search the file userInformation.txt in read mode…
Use the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations. Your application should allow the user to perform these tasks: Task 2: Find the term of any linear sequence given by the rule Term = a * n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.
PYTHON!!!!! A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main: lyst = [3, 1, 7, 1, 4, 10] An example of the program output is shown below: List: [3, 1, 7, 1, 4, 10] Mode: 1 Median: 3.5 Mean: 4.33333333333333 Program produces correct output given input: Custom Test: mode method test Test Contents: import stats assert(stats.mode([3, 1, 7, 1, 4, 10]) == 1) assert(stats.mode([1, 1, 2, 3, 5, 8, 13, 21]) == 1) assert(stats.mode([10, 13, 78, 69, 45, 23, 32, 23]) == 23) Custom Test:…
Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…
End of semester grades are quickly approaching and some nice guy hacker wants to write a function called "raiseGrades" that will take in a list of grades and add 5 to the total of each one. Not to look fishy, if the grade goes over 100, you will need just set it to 100. Return the list back. Example Input: 90, 95, 99 Example Output 95, 100, 100
python language. Instructions are given within the quotations. def is_word_from_letters(word, letters): """ Returns True if word is spelled by rearrange all or some of the letters Otherwise returns False Notes: this is different from uses_only function we wrote before, word not only can use only characters in letters, but the number of times it can use a letter is also limited by what is in letters. For example: is_word_from_letters("book", "bok") should be False because we do not have enough letter 'o'. """ return True
In this challenge, the task is to debug the existing code to successfully execute all provided test files. Python supports a useful concept of default argument values. For each keyword argument of a function, we can assign a default value which is going to be used as the value of said argument if the function is called without it. For example, consider the following increment function: defincrement_by(n,increment=1):returnn+increment The functions works like this: >>>increment_by(5,2)7>>>increment_by(4)5>>> Debug the given function print_from_stream using the default value of one of its arguments. The function has the following signature: defprint_from_stream(n,stream) This function should print the first values returned by get_next() method of stream object provided as an argument. Each of these values should be printed in a separate line. Whenever the function is called without the stream argument, it should use an instance of EvenStream class defined in…
Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
please code in pythonRead in and return a list of review dates. The function should ask the user to enter some review dates This should be entered in the format mm/dd/yyyy (same as that in the file) where dd is two-digit day, mm is two digit month and yyyy is a four digit year e.g. 01/22/2020 The function should return a list containing the specified review dates. :return: a list of review datesYou can take any review date as sample example
You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted. Don’t forget to include descriptive comments in your Python code. Your submission will be assessed using the following Aspects. Does the submission include the is_divisible function from Section 6.4 of the textbook? Does the submission implement an is_power function that takes two arguments? Does the is_power function call is_divisible? Does the is_power function call itself recursively? Does the is_power function include code for the base case of the two arguments being equal? Does the is_power function include code for the base case of the second argument being "1"? Does the submission include correct output for the five test cases?
