c1      |  path --------|----------- t1      | t0/t1 t2      | t0/t1/t2 t3      | t0/t1/t2/t3 x1      | t0/x0/x1 t2      | t0/x0/x1/t2 t3      | t0/x0/x1/t2/t3 t3      | t0/y0/y1/y2/t3 y3      | t0/x0/x2/y3 y4      | t0/x0/x2/y3/y4

i need write q query or code should return smallest distinct delimited string shown below

c1      |  path --------|----------- t1      | t0/t1 x1      | t0/x0/x1 t3      | t0/y0/y1/y2/t3 y3      | t0/x0/x2/y3
