use binary search, cuz i heard the dictionary guys put words in lexicographically sorted manner

it depends on the type of dictionary order, but i suppose it’s the usual ABC order

all you need to know is that dictionaries work like a tree:

first, you have A–Z for every letter (let’s say A) there’s another A–Z, and so on

So if you want a word like "Codeforces" you first look for C, then inside C find o, then d, and continue like this until you get the full word

after some practice you’ll be able to find words much faster but honestly google trans is way faster unless using it distracts you from learning (because you get distracted by using you phone or idk)

binary search

Try inserting all the words into a trie! It's the perfect data structure for dictionaries.
