55. Given a rectangular matrix containing only digits, calculate the number of different 2 × 2 squares in it. [Example] For the output should be differentSquares(matrix) = 6. Here are all 6 different 2 × 2 squares: 1 2 2 2 2 1 2 2 2 2 2 2 2 2 1 2 2 2 2 3 2 3 2 1 [Solution] # def differentSquares(matrix): l = [] total = 0 for i in range(len(matrix) - 1): for j in range(len(matrix[0]) - 1): arr = ..

52. Define a word as a sequence of consecutive English letters. Find the longest word from the given string. [Example] For text = "Ready, steady, go!", the output should be longestWord(text) = "steady". [Solution] # def longestWord(text): l = list() print(ord("a"), ord("z"), ord("A"), ord("Z")) s = "" for i in range(len(text)): if 97

49. Given a string, return its encoding defined as follows: First, the string is divided into the least possible number of disjoint substrings consisting of identical characters for example, "aabbbc" is divided into ["aa", "bbb", "c"] Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character for example, substring "bbb" is replac..

김성훈 교수님의 모두를 위한 딥러닝 시즌2가 나왔습니다. https://www.youtube.com/channel/UCC76Jmsg6SAjdvphzGSJMBQ 이번 강의는 Tensorflow2.0과 Pytorch 2가지 버전으로 새롭게 나왔는데요. 이전 강의도 좋지만 이번 강의를 보시는 것도 좋을 것 같다고 생각됩니다. 모두 즐겁게 공부합시다!

46. Elections are in progress! Given an array of the numbers of votes given to each of the candidates so far, and an integer k equal to the number of voters who haven't cast their vote yet, find the number of candidates who still have a chance to win the election. The winner of the election must secure strictly more votes than any other candidate. If two or more candidates receive the same (maxi..
