These include HackerRank and LeetCode, both of which categorize projects by difficulty level and topic. This approach lets you focus on your areas of interest or the specific skills you need to acquire for particular jobs. AI-Assisted Coding Artificial Intelligence (AI) is reshaping how we learn...
This site is a good place to learn programming languages like C++, Java, Swift, Python, and many more. Users who do very well in all the challenges are given certificates. 2. CheckiO CheckiO is another excellent alternative to LeetCode. ...
Personally, I don’t find as much joy doing LeetCode questions. Rather, I work on LeetCode problems as if I am lifting weights at the gym. While I don’t enjoy lifting weights, I do like reaping the benefits of it. That’s all for today. Let me know what are you building with C...

If you do not use recursion, you can also use the stack to achieve. But the essence is similar. First, state space of the title to a graph. The state is the node in the graph, and the connection between the states is the edge in the graph. Then DFS performs depth-first traversal ...
I've been trying DP questions ( not enough in codeforces, but in leetcode ) and whenever I try to solve this question, I'm stuck at whether I should do it with 1d Array or 2d Array. now now now, I know many of you are going to say solve more problems ( I agree ). Through ...
But here I still summarize a key point, that is: If you do not use the scrolling array technique , then the traversal order depends on the state transition equation. such as: for i in range(1, n + 1): dp[i] = dp[i - 1] + 1 ...
Also using Go as example. After AI performed better than every human, online Go competition effectively collapsed. Everyone can use AI to cheat. An unknown contestant who suddenly performs really well will be challenged on whether they are cheating using AI. ...
To be clear: leetcode is really hard! I was so bad at it at first I avoided doing it because it made me feel stupid to fail these basic easy problems. My friends could do the problems just fine and would act as if they were easy, so I stopped doing leetcode because I didn't wa...
If you need to convert characters (or numeric ASCII values) that are not known in advance (i.e., in variables), you can use something a little more complicated.Note:These functionsonlywork for single-byte character encodings. # POSIX# chr() - converts decimal value to its ASCII character...
