Bonus task | Lesson 10 | Level 10

nameA: AB2B2, nameB: C33 nameA: AB2B2, nameB: C33

Wow, what a task! I'm not sure if CodeGym accepts recommendations, but I think the course would benefit a lot if it included a lesson on possible ways of searching through 2D arrays (I've found 5 in open sources) and, by all means, a good solid lesson on DFS (Depth-First Search), which is actually necessary for this type of tasks. I'm glad there are free materials on this topic on the internet, but it wouldn't hurt to provide the reguired theory here as well.

I'll be back to finish the last three exercises after I graduate from the course.😂

Rectangle Algorithms: { 1, 0, 0, 0} { 0, 1, 0, 0} { 0, 0, 1, 0} { 0, 0, 0, 1} { 1, 1, 0, 0} { 1, 0, 0, 0} { 0, 0, 1, 1} { 0, 0, 0, 1} this arrays contains 4 rectangles. according to the instructions, I assumed that in such a case the number of rectangles should be 0.

Started in 2018 / 2019 --- it's 2023 lol

About "Number algorithms" (task2025), here is a very unique idea: the numbers in the task are called Armstrong numbers. There are only 89 Armstrong numbers in the decimal number system. All 89 are listed here: https://hu.wikipedia.org/wiki/Armstrong-szám or here: https://mathworld.wolfram.com/NarcissisticNumber.html - In a long[] array, put all of them that are less than Long.MAX_VALUE. - Make a loop that returns from this array all elements as an array that are less than the number passed to the getNumbers() method. - Exception: according to the links above, 0 is also an Armstrong number. But CG does not accept zero as an Armstrong number. So take zero out of the long[] array mentioned above. This solution was not my idea, it is from another user. The validator accepts it.

It's been good Java Core. This level has refreshed me from my slump at levels 18 and 19.

for those who do not only want to pass the tasks but also understand how Serialization and inheritance are related, I hope you find this article useful: https://www.geeksforgeeks.org/object-serialization-inheritance-java/

This level demotivated me so much.
