We all think that even if AI gets smarter than us, we can still have fun doing Codeforces. It's a great way to get better at solving programming problems, or just to feel good about tackling tough challenges. But the Codeforces rating system could become broken. So, I propose that we ...
When the sub-problems are abbreviated to the ordinary, we can directly know its solution. Then the original problem can be solved by establishing the connection (transfer) between the recursive functions. Is it a bit like divide and conquer? Divide and conquer refers to dividing the problem ...
LeetCode also has a good collection of SQL problems which are good to improve your SQL query skills and I suggest you take a look at those problems if you want to improve your SQL query skills. Other related SQL queries, Interview questions, and articles: How to join three tables in one...
This leetcode's problem is a favorite question of coding interviews. The data structure we are going to work with is Singly LinkedList. It's super fun. Note: We are not going to use the inbuilt LinkedList class of C# because that is a doubly linked list....
