range34 0212. Reversed sequence Build a function that returns an array of integers from n to 1 where n>0. Example : n=5 --> [5,4,3,2,1] Solution: reverse_seq = lambda n: sorted(range(1, n+1), reverse=True) def reverseseq(n): return list(range(n, 0, -1)) 2023. 2. 13. 0128. Gauß needs help! (Sums of a lot of numbers). Due to another of his misbehaved, the primary school's teacher of the young Gauß, Herr J.G. Büttner, to keep the bored and unruly young schoolboy Karl Friedrich Gauss busy for a good long time, while he teaching arithmetic to his mates, assigned him the problem of adding up all the whole numbers from 1 through a given number n. Your task is to help the young Carl Friedrich to solve this problem .. 2023. 1. 28. 0121. esreveR Write a function reverse which reverses a list (or in clojure's case, any list-like data structure) (the dedicated builtin(s) functionalities are deactivated) Solution: def reverse(lst): result = list() for _ in range(len(lst)): result.append(lst.pop()) return result 2023. 1. 21. 0113. Build a square I will give you an integer. Give me back a shape that is as long and wide as the integer. The integer will be a whole number between 1 and 50. Example n = 3, so I expect a 3x3 square back just like below as a string: +++ +++ +++ Solution: def generate_shape(n: int) -> str: return "\n".join("+" * n for i in range(n)) 2023. 1. 13. 0103. Powers of 2 Complete the function that takes a non-negative integer n as input, and returns a list of all the powers of 2 with the exponent ranging from 0 to n ( inclusive ). Examples n = 0 ==> [1] # [2^0] n = 1 ==> [1, 2] # [2^0, 2^1] n = 2 ==> [1, 2, 4] # [2^0, 2^1, 2^2] Solution: def powers_of_two(n: str) -> list[int]: return [pow(2, i) for i in range(n+1)] 2023. 1. 3. 1229. Parts of a list Write a function partlist that gives all the ways to divide a list (an array) of at least two elements into two non-empty parts. Each two non empty parts will be in a pair (or an array for languages without tuples or a structin C - C: see Examples test Cases - ) Each part will be in a string Elements of a pair must be in the same order as in the original array. Examples of returns in different l.. 2022. 12. 30. 이전 1 2 3 4 ··· 6 다음
