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: Write a function which calculates the average of the numbers in a given list. Note: Empty arrays should return 0. Solution: 1. If 'numbers' is an empty array, 0 is returned. 2. If it is not empty, the average value is returned. import statistics def find_average(numbers): return statistics.mean(numbers) if numbers else 0 statistics.mean() is a Python built-in library that calculates..

Description: You get an array of arrays. If you sort the arrays by their length, you will see, that their length-values are consecutive. But one array is missing! You have to write a method, that return the length of the missing array. Example: [[1, 2], [4, 5, 1, 1], [1], [5, 6, 7, 8, 9]] --> 3 If the array of arrays is null/nil or empty, the method should return 0. When an array in the array is..

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..

Description: Complete the code which should return true if the given object is a single ASCII letter (lower or upper case), false otherwise. Solution: 1. Get the ASCII code of the argument. 2. Check whether the obtained ASCII code corresponds to the alphabet. 3. True if true, false otherwise. def is_letter(s): ascii_num = len(s) == 1 and ord(s) return (ascii_num >= 65 and ascii_num = 97 and asci..
