What video lectures on math analysis and computer science are worth watching?

Question

Mathematics

I would like to find an additional source of information to strengthen knowledge in the mentioned areas at your leisure, in addition to studying material from textbooks.
At the moment I am studying C++ according to the textbook by S. Prata, matan according to Ilyin and Poznyak. The results are not bad, but I want to alternate the ways of studying. The main thing is that the lectures should be interesting, because at my university mathematics is terribly boring, which causes problems with understanding.
Regarding computer science, I am interested in more or less general theoretical areas, for example, architecture or algorithms.
I tried to google - too much variety of material, which makes it very difficult to choose something of high quality.
UPD: language - English with subtitles (at least English) or Russian. I still give priority to English, I need to develop it.
