Write a function that takes an array of numbers and returns the sum of the numbers. The numbers can be negative or non-integer. If the array does not contain any numbers then you should return 0. Examples Input: [1, 5.2, 4, 0, -1] Output: 9.2 Input: [] Output: 0 Input: [-2.398] Output: -2.398 Assumptions You can assume that you are only given numbers. You cannot assume the size of the array. You..

Wolves have been reintroduced to Great Britain. You are a sheep farmer, and are now plagued by wolves which pretend to be sheep. Fortunately, you are good at spotting them. Warn the sheep in front of the wolf that it is about to be eaten. Remember that you are standing at the front of the queue which is at the end of the array: [sheep, sheep, sheep, sheep, sheep, wolf, sheep, sheep] (YOU ARE HER..

Your task is to find the first element of an array that is not consecutive. By not consecutive we mean not exactly 1 larger than the previous element of the array. E.g. If we have an array [1,2,3,4,6,7,8] then 1 then 2 then 3 then 4 are all consecutive but 6 is not, so that's the first non-consecutive number. If the whole array is consecutive then return null2. The array will always have at leas..

This kata is from check py.checkio.org You are given an array with positive numbers and a non-negative number N. You should find the N-th power of the element in the array with the index N. If N is outside of the array, then return -1. Don't forget that the first element has the index 0. Let's look at a few examples: array = [1, 2, 3, 4] and N = 2, then the result is 3^2 == 9; array = [1, 2, 3] ..

Given a string, capitalize the letters that occupy even indexes and odd indexes separately, and return as shown below. Index 0 will be considered even. For example, capitalize("abcdef") = ['AbCdEf', 'aBcDeF']. See test cases for more examples. The input will be a lowercase string with no spaces. Good luck! Solution: def capitalize(s): return [''.join(v.lower() if i%2==1 else v.upper() for i, v i..

This program tests the life of an evaporator containing a gas. We know the content of the evaporator (content in ml), the percentage of foam or gas lost every day (evap_per_day) and the threshold (threshold) in percentage beyond which the evaporator is no longer useful. All numbers are strictly positive. The program reports the nth day (as an integer) on which the evaporator will be out of use. ..

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..

Challenge: Given a two-dimensional array of integers, return the flattened version of the array with all the integers in the sorted (ascending) order. Example: Given [[3, 2, 1], [4, 6, 5], [], [9, 7, 8]], your function should return [1, 2, 3, 4, 5, 6, 7, 8, 9]. Solution: def flatten_and_sort(array): arr = [] for i in array: arr.extend(i) return sorted(arr) Other Solution: from itertools import c..

You are given an odd-length array of integers, in which all of them are the same, except for one single number. Complete the method which accepts such an array, and returns that single different number. The input array will always be valid! (odd-length >= 3) Examples [1, 1, 2] ==> 2 [17, 17, 3, 17, 17, 17, 17] ==> 3 Solution: def stray(arr): import collections return [k for k, v in collections.C..

Write a function that always returns 5 Sounds easy right? Just bear in mind that you can't use any of the following characters: 0123456789*+-/ Good luck :) Solution: def unusual_five(): return int([i for i in str(ord("A"))].pop()) Other Solution: def unusual_five(): return len("five!") def unusual_five(): return ord("")
