The order of "students" in a line is represented by an array of Strings. Position 0 represents the student at the beginning of the line. The student at "pos" is misbehaving, and needs to be moved to the end of the line. Every other student behind the misbehaving student should be moved one closer to the front. If the misbehaving student is the last student in line, then that student should be removed from the line by setting the value at "pos" to be null. The "students" array will always have at least one value, and "pos" will be a valid position in "students".
