Problem Statement
A street on Stanford can be modeled by a number line. Four Stanford students, located at positions , , and along the line, want to take an UberXL to Berkeley, but are not sure where to meet the driver. Find the smallest possible total distance walked by the students to a single position on the street. (For example, if they were to meet at position , then the total distance walked by the students would be , where the distances walked by the students at positions , , and are summed in that order.)
