Question

C++

5. (6 points) Write a function split_vector that receives a source vector of Date (from Project 2) values and a target Date value, and passes back two vectors of Date. The first passed back vector will contain (copies of) the items from the source vector that have a value that is before the target value (as defined by operator<) and the second passed back vector will contain (copies of) all other items (i.e., those with values that are on or after the target). Note that the source vector is not in any particular order, and the source vector must not be modified by this function. E.g., if the source vector has elements {10/23/2015, 7/10/2012, 2/4/2016, 3/15/2017, 9/4/2010) and the target is 11/15/2015, then the first passed back vector will contain 10/23/2015, 7/10/12, 9/4/2010) and the second passed back vector will contain 2/4/2016, 3/15/2017
