WebRecursion is the technique of making a function call itself. This technique provides a way to break complicated problems down into simple problems which are easier to solve. … Keep holes in the vector and maintain another vector saying which entries are filled. A the end of a recursive call shift the entries so that there are no holes between the subsample s and newval. But now I switch copying by shifting with additional work for the second vector - probably bad idea.
