LeetCode 1929: Concatenation of Array(EASY)
Today I learned how to duplicate an array.
I solved it in two ways:
1οΈβ£ Using +
β‘οΈ Combine the array with itself
2οΈβ£ Using extend()
β‘οΈ Add the same elements again to the array.
Both are simple ways to create a concatenated array.

Teaching is one of the best ways to learn.As I prepare tomorrow's lecture on Two Pointers, I keep discovering concepts I missed before. Every time I teach, I deepen my own understanding.
Sometimes the best student is the teacher.

Waking up after setting your alarm and then thinking, "Should I sleep more like 30 minutes?" is on a whole other level. It's a trick because I know I'm not going to wake up, so let's see if we succeed and how things turn out after 6 AM in the morning and also in the afternoon. I'm not going to sleep back, decided αα΅ααα π. #random@theJourneyy101

Last year, I solved this problem in a very complicated way. Today, I looked at it again and solved it with a much simpler and better approach.
The biggest lesson is not just solving problems, but seeing how much you improve over time. The time and effort you spend today build your problem-solving skills for tomorrow.
Keep practicing consistently, learn from every problem, and always try to think about different approaches. Every problem is an opportunity to improve.

Hello everyone! π
I wanted to let you know that I'll be offline for about one week. I won't have access to my PC, phone, or the internet for personal reasons.
During this time, I've given admin access to two trusted friends so the community can stay active. Please support them and continue helping each other.
I'll be back in a week. I'll definitely miss this amazing community! β€οΈ If possible, I'll also record a YouTube video.
Thank you all for being part of this journey. Take care, keep learning, and see you soon!
Much love to all 207 of you! β€οΈ
