Notes: "🔒" means your subscription of LeetCode premium membership is required for reading the question.The similarity relation is transitive. For example, if "great" and "good" are similar, and "fine" and "good" are similar, then "great" and "fine" are also similar. And the similarity is also symmetric. So, "great" and "fine" being similar is the same as "fine" and "great" is similar. A word is always similar to itself. Your solution never finished running in time, it was stopped in between. So, there is definite way to say if the code was correct or not. At times, this means that your code contains an infinite loop, and your program will never stop executing. In other cases, it may mean that your program will terminate, but not within the time limit indicated.About Solution 2 Growth In Java Hackerrank Dimensions.
