This article is contributed by Jatin Goyal. Instead of generating all strings from the grid and the checking whether it exists in dictionary or not , we can simply run a DFS on all words present in dictionary and check whether we can make that word from grid or not.

Input: str = geekOutput: geek geke gkee egek egke eegk eekg ekge ekeg kgee kege keeg. The idea is to add all the characters of a string to a set. Mastering them enables you to write code that is efficient, leading to software that runs faster and consumes less memory. The outer loop picks all strings one by one. For instance, the words bat and tab represents two distinct permutation (or arrangements) of a similar three letter word. This can be done in more simpler way by using the property of the %s format specifier . Writing code in comment?
