I teach Algorithms at the University of Cambridge. Through this channel I welcome anyone in the world to attend my lectures.
A few good habits will help you avoid common off-by-one errors. Why do computer scientists like to count from zero rather than one?
This video introduces insertsort, one of the simplest and most natural sorting algorithms. In passing we introduce preconditions, postconditions, invariants, assertions and the philosophy of programming by contract.
