Even numbers in an array Given an array of numbers, return a new array of length number containing the last even numbers from the original array (in the same order). The original array will be not empty and will contain at least "number" even numbers. For example: ([1, 2, 3, 4, 5, 6, 7, 8, 9], 3) => [4, 6, 8] ([-22, 5, 3, 11, 26, -6, -7, -8, -9, -8, 26], 2) => [-8, 26] ([6, -25, 3, 7, 5, 5, 7, -3, 23], 1) => [6] Solutio.. 2022. 5. 6.
Sum of odd numbers Description: Given the triangle of consecutive odd numbers: 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 ... Calculate the sum of the numbers in the nth row of this triangle (starting at index 1) e.g.: (Input --> Output) 1 --> 1 2 --> 3 + 5 = 8 Solution: 1. Add up all 'n' numbers. 2. Find the odd number by the added number. 3. It returns after adding 'n' odd numbers from the last. def row_sum_odd_num.. 2022. 4. 28.
String ends with? Description: Complete the solution so that it returns true if the first argument(string) passed in ends with the 2nd argument (also a string). Examples: solution('abc', 'bc') # returns true solution('abc', 'd') # returns false Solution: 1. Return True if the last digit of 'string' is the same as 'ending'. 2. If 'ending' is an empty string, return True. 3. If not, return False. def solution(strin.. 2022. 4. 21.
Sum of two lowest positive integers Description: Create a function that returns the sum of the two lowest positive numbers given an array of minimum 4 positive integers. No floats or non-positive integers will be passed. For example, when an array is passed like [19, 5, 42, 2, 77], the output should be 7. [10, 343445353, 3453445, 3453545353453] should return 3453455. Solution: 1. Find the two smallest numbers. 2. Returns the sum o.. 2022. 4. 19.
How Green Is My Valley? Description: Input : an array of integers. Output : this array, but sorted in such a way that there are two wings: the left wing with numbers decreasing, the right wing with numbers increasing. the two wings have the same length. If the length of the array is odd the wings are around the bottom, if the length is even the bottom is considered to be part of the right wing. each integer l of the le.. 2022. 4. 4.
Reverse words Description: Complete the function that accepts a string parameter, and reverses each word in the string. All spaces in the string should be retained. Examples "This is an example!" ==> "sihT si na !elpmaxe" "double spaces" ==> "elbuod secaps" Solution: 1. Separate text based on space. 2. Turn over the separated text and put it in an array. 3. Convert the text in the array to a string with space.. 2022. 3. 28.
