2. Write a Python program that uses a function to find and return the factorial of a positive integer n. The function the receives a value and returns its factorial. If the passed parameter is negative, the function return the string "ERROR". Factorial of zero is one. Test your function. If n is a positive integer, n factorial denoted by nl is a product of all positive integers less than or equal to n. It is defined by =n(n-1)(n-2)..(2)(1) As a special case: 0! 1 3. In a new program, use the function you wrote in question 2 to print the factorials of values from 1 to 10. Use for loop.

python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments. How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...')

write a python program 9. You are a class teacher at a kindergarten school. As a task, you asked your students to write a paragraph. Unfortunately, you notice that most of the students did not use capital letters correctly. Your task is to write a function which takes a string as its only parameter and returns a new copy of the string that has been correctly capitalized. Your function should: Capitalize the first letter in the string Capitalize the first letter after a full-stop, exclamation mark or question mark • Capitalize the word “i" if it is in lowercase. Summary: You have to write a function that reads a string from the user and capitalizes. The string is then returned and displayed. Sample Input ('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily. do you know my pet dog's name? i love my pet very much.') Sample Output My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do you know my pet dog's name? I…
Write a MATLAB function “creaievecMToN” that will create and return a vector of integers from m to n (where m is the first input argument and n is the second), regardless of whether m is less than n or greater than If m is equal io n, the “vector” will just be l x 1.
Write a c++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Your program should have the following functions: (a) WriteafunctiongetDatethatpromptsausertoenteradateasastringandreturns it. (b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers. (c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int. (d) Write a function convertMonths that takes as its parameter a month as a string and returns a corresponding number from 1 to 12 (1 for January, . . . , 12 for Decem- ber).
Going missing Some calculations involving blank values may give different results to what you might expect. For example, when you pass a blank value into the AND() function, it is treated as TRUE. This is often unhelpful. To make blanks behave in a sensible way in calculations, you must first convert them to be "not available" using NA(). This function takes no inputs, and returns a missing value. To convert a blank value to a missing value, use this pattern. =IF(ISBLANK(cell), NA(), cell) Instruction In column H, use AND() to find women who have kids and get benefits. In column I, convert the blanks in column G to missing values. In column J, again find women who have kids and get benefits, this time using column I rather than G. please show the formula used to "has kids and gets benefits" , "gets benefits with missing values", has kids and gets benefits".

Assume (or you can create it) a function for detecting prime numbers is created. Then, write a script file in MATLAB that will call that function for all number between 600 and 999, find the twin primes, safe primes, sexy primes, and Mersenne primes and "good" friends. Note: I already have the function (isprime(num)). I want the script file following the above conditions.
Pb#1: For several values of x, confirm that eix = cos x + i sin x Pb#2: An object thrown vertically with a speed vo reaches a height h at time t, where h= vo*t - gt2 Write and test a function that computes the time t required to reach a specified height h, for a given value of vo. The function's inputs should be h, vo, and g. Test your function for the case where h=100 m, vo=50 m/s. and g=9.81 m/s2. Interpret both answers. (MATLAB)
2. Write the definition of a bool function named BooleanMode () whose header is bool BooleanMode (bool data[), int n) Given that n represents the size of data, the function returns the truth value that appears the most in data. If there is an equal number of both truth values in data, the function returns the truth value that appeared first. For instance, if data = [true, true,false, false,false, true,falsel, then the function will return false. Impl
Implement a function that checks if a number is within a given range. It should accept the range (minimum value and maximum value) and the value to be checked (Xmin ≤ X ≤ Xmax). The function will return true if the given value is within that range, otherwise will return false.
