Due to another of his misbehaved, the primary school's teacher of the young Gauß, Herr J.G. Büttner, to keep the bored and unruly young schoolboy Karl Friedrich Gauss busy for a good long time, while he teaching arithmetic to his mates, assigned him the problem of adding up all the whole numbers from 1 through a given number n. Your task is to help the young Carl Friedrich to solve this problem ..

Your Job Find the sum of all multiples of n below m Keep in Mind n and m are natural numbers (positive integers) m is excluded from the multiples Examples sumMul(2, 9) ==> 2 + 4 + 6 + 8 = 20 sumMul(3, 13) ==> 3 + 6 + 9 + 12 = 30 sumMul(4, 123) ==> 4 + 8 + 12 + ... = 1860 sumMul(4, -7) ==> "INVALID" Solution: def invalid_value(func): def wrapper(n, m): return (n

Suzuki is a monk who climbs a large staircase to the monastery as part of a ritual. Some days he climbs more stairs than others depending on the number of students he must train in the morning. He is curious how many stairs might be climbed over the next 20 years and has spent a year marking down his daily progress. The sum of all the stairs logged in a year will be used for estimating the numbe..

You are given the length and width of a 4-sided polygon. The polygon can either be a rectangle or a square. If it is a square, return its area. If it is a rectangle, return its perimeter. Example(Input1, Input2 --> Output): 6, 10 --> 32 3, 3 --> 9 Note: for the purposes of this kata you will assume that it is a square if its length and width are equal, otherwise it is a rectangle. Solution: def ..

Kids drink toddy. Teens drink coke. Young adults drink beer. Adults drink whisky. Make a function that receive age, and return what they drink. Rules: Children under 14 old. Teens under 18 old. Young under 21 old. Adults have 21 or more. Examples: (Input --> Output) 13 --> "drink toddy" 17 --> "drink coke" 18 --> "drink beer" 20 --> "drink beer" 30 --> "drink whisky" Solution: DRINKS = { "Childr..

Palindrome strings A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. This includes capital letters, punctuation, and word dividers. Implement a function that checks if something is a palindrome. If the input is a number, convert it to string first. Examples(Input ==> Output) "anna" ==> true "walter" ==> false 12321 ==> true 123456 =..

Define a method hello that returns "Hello, Name!" to a given name, or says Hello, World! if name is not given (or passed as an empty String). Assuming that name is a String and it checks for user typos to return a name with a first capital letter (Xxxx). Examples: * With `name` = "john" => return "Hello, John!" * With `name` = "aliCE" => return "Hello, Alice!" * With `name` not given or `name` =..

Given an array of integers. Return an array, where the first element is the count of positives numbers and the second element is sum of negative numbers. 0 is neither positive nor negative. If the input is an empty array or is null, return an empty array. Example For input [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, -11, -12, -13, -14, -15], you should return [10, -65]. Solution: def sorted_arr(func): def w..

Write a function named sumDigits which takes a number as input and returns the sum of the absolute value of each of the number's decimal digits. For example: (Input --> Output) 10 --> 1 99 --> 18 -32 --> 5 Let's assume that all numbers in the input will be integer values. Solution: def get_str_number(func): def wrapper(number): return func(str(number).replace("-", "")) return wrapper @get_str_nu..

Your task is to sum the differences between consecutive pairs in the array in descending order. Example [2, 1, 10] --> 9 In descending order: [10, 2, 1] Sum: (10 - 2) + (2 - 1) = 8 + 1 = 9 If the array is empty or the array has only one element the result should be 0 (Nothing in Haskell, None in Rust). Solution: def sort(func): def wrapper(arr): return func(sorted(arr, reverse=True)) return wrap..
