   Given        a        text     file    of      many     lines,     where   fields  within    a   line
    are    delineated     by        a   single  'dollar' character,   write     a    program
   that      aligns      each    column   of     fields      by     ensuring   that   words    in   each
  column       are     separated   by     at     least       one     space.

justified,    right   justified,   or   center justified   within      its   column.
