I always trusted Spring and bought it, but I was hesitant to buy this course. I wondered if it would be better to prepare for the coding test with Python. I wondered if the general content would be meaningful in covering the generics and collections that I had already learned. But the more I listened to the course, the more I thought that it was a good idea to buy it. If it weren't for this course, I think I wouldn't have been able to properly prepare for the coding test. Even if it wasn't an algorithm problem, when solving a problem, if I looked at the method and function and applied it once, I couldn't use it again. But after listening to this course and exploring it with the principles, it was much better and the range of application expanded. I became more interested in algorithms and had fun with them. Now I think I'll be able to study algorithms and Spring more easily. Thank you!!!
