Hi,

I'm trying to sort a map based on second, but I get all kinds of compiler errors and I have no idea what's wrong. A simple _1 > _2 works fine, but that compares the maps themselves.

Also, is there a better way to write the copy from map to vector or to sort the map in general?

maps are already sorted! see the third template argument. a simple vec.insert(vec.end(), map.begin(), map.end()) will copy it. did you need something else? -- Cory Nelson
