Sets are in...

Input

Suppose we have 
set1
with elements 
a, b
and 
set2
with elements 
a, c, e
.
  • Rows. Each row in the table is a set. The first element in each row is the name of the set.
    • set1ab
    set2ace
  • Columns. Each column in the table is a set. The first element in each column is the name of the set.
    • set1set2
    aa
    bc
    e
    Notice the space character at the beginning of the last line. Without it, element 
    e
    would belong to 
    set1
    .
  • Guess. The program will apply heuristics to decide if the sets in your data are expressed by row or by column.
