Hi codeforces crew so i want to learn the divide and conquer but i cannot find the starter question like if u say are u dump? go ask ai!I alr did.I used chat gpt/gemini non can give me normal starter question ;-; and there codes is much hard to understand becouse they use complex struct or thing like that wich i hate so the only hope is ask help from humans like yall and before u give thanks for helping :) (u can give me site example to learn from or some ez questions to solve it related to the divide and conquer)
to the dislikers in my whole money i bet yall dont even see what i even wrote .But still its sad of seeing a ppl like yall.Yall useless to the learners and sharing your negativity with us if im saying lie proof it anyways this post is for education so if u change your mind and help me learning it thanks from now on
in a god's green earth non of the codeforces member cant help this poor bud? as like a meme of the ishowspeed "pls i need this im kinda poor in devide and conquer" ;-;
have you ever learned the Segment Tree? it's a little hard but divide and conquer is the core concept of it. Try to learn this, it's a trump card of interval problem
welp i know the seg tree! but idk the merge of it ig i need to go back and learn it ig? thanks for help same to CS_alpha (i can't write reply to him couse codeforces let me write comment once 10 min) btw until here i known tht for being "same" with binary search as both just searchs array in same way
Learn mergeSort
what is merge sort?
:) A sorting algorithm

Do you want to learn divide and conquer because you are interested in it? Or do you want to learn divide and conquer because you think it will increase your rating?
If you think the first one, go for it. If you think the second one, you're wrong, divide and conquer rarely appears in problems rated $$$ \lt 1800$$$. It seems like you are thinking the second one, but I don't know
Don't use AI for learning competitive programming. Not that it doesn't know what it's talking about but rather it is extremely easy to misuse as it does exactly what you want it to. There are tons of free resources like USACO Guide and Competitive Programmer's Handbook and you choose to use a text prediction algorithm?
You should probably know basic programming to do competitive programming. A struct is literally a simplification of a class. If you don't know something look it up
This is true, but it's because if they see a newbie making a post called "Divide and Conquer needa help" it's probably downvote worthy
If you REALLY need an easy divide and conquer problem to survive... 1234D - Distinct Characters Queries (this is solvable without divide and conquer too!)
But right now, if you aren't interested in divide and conquer, you should be improving on skills like greedy, math, prefix sums, basic number theory, binary search that are all actually useful at your level (and mine!)

ayy yooo thanks while i was tyrna learn it i just said bitmask is easier fr but thanks now i know where to start from
Divide and conquer is literally dividing the problems in smaller parts, usually resulting in logarithmic time. E.g. binary search (divides into 2 until element is found), quick sort (also divides into 2 and sorts each half, quarter, etc.), or even the euclidean algorithm (GCD).
Divide and conquer isn't really a specific algorithm/block of code, it's just a technique.
