//  Copy a vector that holds the values from 1 to 9 inclusive, into three other
//  containers.
//  Use an inserter, a back_inserter, and a front_inserter, respectivly to add
//  elements to these containers.
//  Predict how the output sequence varies by the kind of inserter and verify
//  your predictions
//  by running your programs.
