Binary Search tutorial (C++ and Python)

This is the most comprehensive lecture on the binary search. Find the target value, or the first value satisfying some condition, or approximate sqrt(x) up to some precision. Watch this lecture if you practice for competitive programming or for coding interviews. See the pinned comment for links and my implementation. Consider turning captions on and setting the speed to x1.25. Please give me suggestions about the format of a lecture or about topics for future lectures.
