👉 In mathematical notation, "headway" is defined as a measure of time between two events. It's used in computer science and mathematics to describe how fast or slow an algorithm can execute given its input size. For example, if we have two events A and B, with the event A taking 3 seconds to execute and the event B taking 5 seconds, then the headway between them is the difference between their execution times: 2 seconds. This measure is often used in computer science
