Then print all anagrams by linearly traversing the sorted array. Then, by calling .sort() on that array all the strings are sorted in descending order, in this case alphabetically. If a string is not an anagram with any other string in the array, it remains in the array. Let’s look at that again. Any characters can be deleted from any of the strings. I created almost all solutions in 4 programming languages – Scala, Javascript, Java and Ruby. So if we take our base string and convert it to an alphabetized string of characters it would stand to reason that any anagram of that base string would convert to an identical alphabetized string. The majority of the solutions are in Python 2. Code language: PHP (php) So you could find 2 such integers between two sets, and hence that is the answer. My Hackerrank profile.
