About this video
EDEXCEL 1CP2 Specification Reference - Topic 1A: 1.1.1 - 1.2.7
More than one algorithm can often be used to solve the same problem, so which one should you choose? In this video we take a look how to compare algorithms for solving the same problem based on their time efficiency.
Don't forget, whenever the blue note icon appears in the corner of the screen, that is your cue to take notes about the content being shown on the current slide.
