In this Kata, you will be given a string that may have mixed uppercase and lowercase letters and your task is to convert that string to either lowercase only or uppercase only based on: make as few changes as possible. if the string contains equal number of uppercase and lowercase letters, convert the string to lowercase. For example: solve("coDe") = "code". Lowercase characters > uppercase. Cha..

In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example: 5! = 5 * 4 * 3 * 2 * 1 = 120. By convention the value of 0! is 1. Write a function to calculate factorial for a given input. If input is below 0 or above 12 throw an exception of type ArgumentOutOfRangeException (C#) or IllegalArgumentException (..

Take an integer n (n >= 0) and a digit d (0

Your task is to make a function that can take any non-negative integer as an argument and return it with its digits in descending order. Essentially, rearrange the digits to create the highest possible number. Examples: Input: 42145 Output: 54421 Input: 145263 Output: 654321 Input: 123456789 Output: 987654321 Solution: def descending_order(num): return int("".join(sorted([i for i in str(num)], r..

You will be given an array and a limit value. You must check that all values in the array are below or equal to the limit value. If they are, return true. Else, return false. You can assume all values in the array are numbers. Solution: def small_enough(array, limit): return max(array)

Task You will be given an array of numbers. You have to sort the odd numbers in ascending order while leaving the even numbers at their original positions. Examples [7, 1] => [1, 7] [5, 8, 6, 3, 4] => [3, 8, 6, 5, 4] [9, 8, 7, 6, 5, 4, 3, 2, 1, 0] => [1, 8, 3, 6, 5, 4, 7, 2, 9, 0] Solution: def sort_array(source_array): a,b = [],[] for i, v in enumerate(source_array): if v%2==1: a.append(v) b.ap..

Task Given a list of digits, return the smallest number that could be formed from these digits, using the digits only once (ignore duplicates). Notes: Only positive integers will be passed to the function (> 0 ), no negatives or zeros. Input >> Output Examples minValue ({1, 3, 1}) ==> return (13) Explanation: (13) is the minimum number could be formed from {1, 3, 1} , Without duplications minVal..

Given two numbers and an arithmetic operator (the name of it, as a string), return the result of the two numbers having that operator used on them. a and b will both be positive integers, and a will always be the first number in the operation, and b always the second. The four operators are "add", "subtract", "divide", "multiply". A few examples:(Input1, Input2, Input3 --> Output) 5, 2, "add" --..

In a factory a printer prints labels for boxes. For one kind of boxes the printer has to use colors which, for the sake of simplicity, are named with letters from a to m. The colors used by the printer are recorded in a control string. For example a "good" control string would be aaabbbbhaijjjm meaning that the printer used three times color a, four times color b, one time color h then one time ..

Build Tower Build a pyramid-shaped tower given a positive integer number of floors. A tower block is represented with "*" character. For example, a tower with 3 floors looks like this: [ " * ", " *** ", "*****" ] And a tower with 6 floors looks like this: [ " * ", " *** ", " ***** ", " ******* ", " ********* ", "***********" ] Solution: def tower_builder(n_floors): nums = [i>0 and i*2+1 or 1 for..
