Python task You must write a function control (p_nr) that calculates and returns the control digit in a 10-digit social security number if you send in the first 9 digits in the form of a string. The rules for calculating the check digit in a social security number are as follows:The numbers are multiplied alternately by 2 and 1 and then the products are summed. For a two-digit product, the sum of its numbers is calculated. The sum is then subtracted from the nearest higher tens to obtain the check digit.To calculate the check digit for the social security number with the first 9 digits 811218987, perform the following setup: 8 1 1 2 1 8 9 8 7 2 1 2 1 2 1 2 1 2 16 1 2 2 2 8 18 8 141 + 6 + 1 + 2 + 2 + 2 + 8 + 1 + 8 + 8 + 1 + 4 = 44The check digit is 50-44 = 6 # test personal_number = input () control_digit = control(personal_number) print(control_digit)
PHP Write a function to check weather a string is all uppercase or not. Your function should return true or false
A spoonerism is when the first letters / sounds of two words are transposed onto one another. Create a function that takes a two-word string and performs a spoonerism on the phrase. Examples spoonerise ("history lecture") "listory hecture" spoonerise("loud noises") → "noud loises" spoonerise("chow mein") → "mow chein" spoonerise ("edabit rules!") Notes → "redabit ules!" • Only two words will be parsed into the function. Don't worry about handling more than two. • You won't always just have to swap the first letters, take care to notice which letters have been switched in the examples (notice the difference between vowel-starting and consonant-starting words).
PHP ATM machines allow 4 or 6 digit PIN codes and PIN codes cannot contain anything but exactly 4 digits or exactly 6 digits. *With user input ($pinNumbers), create a function that takes a string and returns true if the PIN is valid and false if it's not. Examples validatePIN("$1234") ➞ true validatePIN("12345") ➞ false validatePIN("a234") ➞ false validatePIN("") ➞ false Notes ● Some test cases contain special characters. ● Empty strings must return false.
JS Write a function named "tweets" that takes a string as a parameter. If a message can hold at most 280 characters, calculate the smallest number of messages needed to hold all of the text in the input. The function should return the number it calculated.
Create a function that determines how many number pairs are embedded in a space-separated string. The first numeric value in the space-separated string represents the count of the numbers, thus, excluded in the pairings. Examples number_pairs("7 1 2 1 2 1 3 2") 2 // (1, 1), (2, 2) number_pairs ("9 10 20 20 10 10 30 50 10 20") 3 // (10, 10), (20, 20), (10, 10) number_pairs("4 2 3 4 1") → 0 // Although two 4's are present, the first one is discounted.

Calculate the wage and return it Do the function call and print a message saying that " ...... is your wage" Add a condition to the function . If the number of hours exceeds 40 hours then assign a 5% bonus to the wage, if it's between 30-40 assign 3% bonus to the wage. submit your PHP file and screenshot of your output
Create a function which returns the type of triangle, given the side lengths. Return the following values if they match the criteria. • No sides equal: "scalene" • Two sides equal: "isosceles" • All sides equal: "equilateral" • Less or more than 3 sides given: "not a triangle" Examples get_triangle_type([2, 6, 5]) "scalene" get_triangle_type([4, 4, 7]) "isosceles" get_triangle_type([8, 8, 8]) "equilateral" get_triangle_type([3, 5, 5, 2]) → "not a triangle"

In Java scripts A number is called a Disarium when the sum of its digits in their respective order is the number itself. Create a function that determines whether a number is a Disarium or not. Examples isDisarium (75) – false //7^1 + 5 ^ 2 = 7 + 25 = 32 Disarium (135) // 1^1 + 3 ^ 2 + 5 ^ 3 = 1 + 9 + 125 - is true = 135 isDisarium (544) - false Disisarium (518) → is true
