You get an array of numbers, return the sum of all of the positives ones. Example [1,-4,7,12] => 1 + 7 + 12 = 20 Note: if there is nothing to sum, the sum is default to 0. Solution: def positive_sum(arr): return sum(map(remove_negative, arr)) def remove_negative(i: int): return i if i >= 0 else 0

Given a 2D ( nested ) list ( array, vector, .. ) of size m * n, your task is to find the sum of the minimum values in each row. For Example: [ [ 1, 2, 3, 4, 5 ] # minimum value of row is 1 , [ 5, 6, 7, 8, 9 ] # minimum value of row is 5 , [ 20, 21, 34, 56, 100 ] # minimum value of row is 20 ] So the function should return 26 because the sum of the minimums is 1 + 5 + 20 = 26. Note: You will alwa..

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..

Description: Write a function that takes an array of strings as an argument and returns a sorted array containing the same strings, ordered from shortest to longest. For example, if this array were passed as an argument: ["Telescopes", "Glasses", "Eyes", "Monocles"] Your function would return the following array: ["Eyes", "Glasses", "Monocles", "Telescopes"] All of the strings in the array passe..

Description: Simple, given a string of words, return the length of the shortest word(s). String will never be empty and you do not need to account for different data types. Solution: 1. Count the number of letters in each word. 2. Returns the smallest number of characters. def find_short(s): return min(list(map(len, s.split())))

Description: Welcome. In this kata, you are asked to square every digit of a number and concatenate them. For example, if we run 9119 through the function, 811181 will come out, because 92 is 81 and 12 is 1. Note: The function accepts an integer and returns an integer Solution: 1. Separate the numbers by one digit. 2. Square each of the separated numbers. 3. Return the squared numbers side by si..

Description: Find the sum of the odd numbers within an array, after cubing the initial integers. The function should return undefined/None/nil/NULL if any of the values aren't numbers. Note: Booleans should not be considered as numbers. Solution: 1. If the element in the array is not of type 'int', None is returned. 2. If the cube of the remaining elements is odd, the values ​​are added. 3. Retu..

Description: Given an array of integers, return a new array with each value doubled. For example: [1, 2, 3] --> [2, 4, 6] Solution: 1. Get the elements out of the array. 2. Multiply the element by 2 and put it back into the array. 3. Return an array. def maps(a): return list(map(lambda x: x * 2, a)) The lambda function is an anonymous function and is suitable for simple calculations.

Description: Given an array of integers of any length, return an array that has 1 added to the value represented by the array. the array can't be empty only non-negative, single digit integers are allowed Return nil (or your language's equivalent) for invalid inputs. Examples For example the array [2, 3, 9] equals 239, adding one would return the array [2, 4, 0]. [4, 3, 2, 5] would return [4, 3,..

Description: Your team is writing a fancy new text editor and you've been tasked with implementing the line numbering. Write a function which takes a list of strings and returns each line prepended by the correct number. The numbering starts at 1. The format is n: string. Notice the colon and space in between. Examples: number([]) // => [] number(["a", "b", "c"]) // => ["1: a", "2: b", "3: c"] S..
