# When the multiplicities are all zero or one, multiset operations
# are guaranteed to be equivalent to the corresponding operations
# for regular sets.
#
# Given counter multisets such as:
# cp = Counter(a=1, b=0, c=1)
# cq = Counter(c=1, d=0, e=1)
#
# The corresponding regular sets would be:
# sp = {'a', 'c'}
# sq = {'c', 'e'}
#
# All of the following relations would hold:
# set(cp + cq) == sp | sq
# set(cp - cq) == sp - sq
# set(cp | cq) == sp | sq
# set(cp & cq) == sp & sq
# (cp == cq) == (sp == sq)
# (cp != cq) == (sp != sq)
# (cp <= cq) == (sp <= sq)
# (cp < cq) == (sp < sq)
# (cp >= cq) == (sp >= sq)
