Optimal memory reallocation and the golden ratio

This is based on a neat little post that I saw on Simon Frankau‘s blog that I thought I’d provide a few more details on, as well as bringing it to a wider audience. Some higher-level data structures in object-oriented programming languages have dynamic memory allocation. This is used to create objects (usually things that behave like lists) that can grow and shrink as the program executes. When initializing a regular array in C or Java, you have to specify the size of the array on creation, for example with

int myArray[] = new int[10];
