Elements of Programming Interviews Greedy algorithms mostly used for optimizing (minimize, maximize) a set of choices examples counting change optimizing intervals often involves sorting first doesn’t always lead to optimal solution, but can provide insight Go Useful packages: bufio, sort, os, strconv, strings There are two ways to sort user defined types. One way is to satisfy sort.Interface by defining Len, Swap, and Less methods. The other is to call sort.Slice with a closure that satisfies the Less method: ...
