You literally can’t lose.

the use of c++ was the best for me, better than other courses, finally i can solve problems using recursive and understand a lot of things .a small suggestion to the creators other courses are popular due to the use of graphics and animations in the videos, so, if you can enhance that part a bit because your content is pure gold and please add real interview question from big companies another thing, please expose more of your content by making more videos available to view before purchase, i almost did not buy this course because of this Keep up the good work and many thanks :)

5 STARS - Feeling very prepared for my upcoming interview - the explanations are very clear and helpful.
