Hello, I am Gustavo from Brazil. I would like some tips to help me improve. Currently, I can solve problems rated around 800 in Div. 4. I can solve problems A, B, and C in Div. 4 contests, but no more than that. In Div. 3, I can sometimes solve problem A, but I don’t ...
To solve a problem using recursion, there must be a recursive termination condition (the infiniteness of the algorithm), which means that the recursion will gradually shrink to the normal size. Although the following code is also recursive, it is not an effective algorithm because it cannot end...
“Bill Gates would have likely borrowed books from the library and typed out the code verbatim,” Larson says, “Today, we have access to amazing tools that speed up the process.” That’s one of the many things Edward Kim, the Vice President of Education at Code Ninjas, and Larson can...
I provided all the AIs with the same prompt, "Solve Leetcode 214. Shortest Palindrome." While I could have asked follow-up questions, I chose to only consider the initial response. It is unclear whether any of these models were pre-trained on Leetcode data. I tested these models because...
Most algorithm competitions take place on specialized online platforms, attracting as many as tens of thousands of international participants per contest.
