I had never solved an algorithm problem, but I thought I should start preparing slowly from now to prepare for a coding test when I get a job later, so I looked for several algorithm lectures and ended up taking this lecture. At first, I thought C++ would be difficult, so I tried Python, but the algorithm textbook that the instructor made was well-made, so I started with C++ with the mindset of trying C++ first and then moving to Python if it was difficult. Now, C++ is the easiest to use when solving problems! The lectures and textbooks are constantly updated, and the questions are well-answered, so I highly recommend this lecture.
