This was made as assignment from FOS

THE TASK: Write a program in c# that can filter a list of strings. It should pass only six letter strings that are composed of two concatenated smaller strings that are also in the list.

For example, given the list

al, albums, aver, bar, barely, be, befoul, bums, by, cat, con, convex, ely, foul, here, hereby, jig, jigsaw, or, saw, tail, tailor, vex, we, weaver

The program should return

albums, barely, befoul, convex, hereby, jigsaw, tailor, weaver

Because these are a concatenation of two other strings:

al + bums => albums bar + ely => barely be + foul => befoul con + vex => convex here + by => hereby jig + saw => jigsaw tail + or => tailor we + aver => weaver
