Strict subset and strict superset

[Christine Lee]

Can anyone please provide me with an example of strict subset and strict
superset? I'm still quite confused....aren't they technically the same
thing (in terms of writing the code)?

Thanks in advance!

strict subset of:
{ "a" "b"}
can either be
{"a"}
or
{"b"}

but cannot be
{"a" "b"}
------------------------------------------------

strict superset of
{"a"}

is any set contains "a"
but not the set {"a"}

Thank you!
