My favorite data structure is the Array.
P.S : If you are coming from a Java background, you feel DSA is quite conceptual and brilliant subject if you work with Java.
i love tries! got introduced into those in cs50 and did a "real" implementation in the ml course at my uni. Have been in love with them ever since. In a trie - its like every node you navigate to makes up a piece of information (sort of like a treasure hunt where each step leads to the next clue and so on) and by the end - u retrieve the full information! super exiting :)
HashMaps and Linked Hashset.
But I love the array in PHP.
They cover so much, they are Hashmaps, Hashsets, ordered Maps, Stacks(derived), Queues(derived) and of course, arrays too :P
Personally I love hashmaps, they are an elegant way to quickly and efficiently store unsorted data in an organized fashion. I typically use them in situations such as spatial hashing, which makes many of my collision based algorithms so much more efficient. I also use them for situations where I need only one of each type, as hashmaps can only have a single key to value relationship. Overall their O(1) nature and their intrinsic properties make them a favorite for me!
My favourite data structure is the one that gets the job done efficiently. /joke
To give a serious answer, my most used, and therefore most often favourite would be a map. Knowing the various underlying implementations is really fun and important in order to make a good performance decision.
I found this site helpful in visualising the various algorithms and data structures cs.usfca.edu/~galles/visualization...
Right Now, it's Stack. I only know two, Stack and Queue.
Why Stack ? coz it pops well. :)
😂🤩👏
HashMap (
<String, Object>
obviously).Basic immutable and enumerable collection. Often all you need.
Definitely Array 😄
