The difference between $* and $@ lies in the way they behave when they occur inside double quotes: $* behaves in the normal way, whereas $@ creates a separate double-quoted string for each command-line argument. That is, "$*" behaves as if you had written "$1 $2 $3", whereas "$@" behaves as if you had written "$1" "$2" "$3".

# Bijection from integers to rationals, showing rational numbers are countably infinite.

# Note that f is a bijection from positive integers to positive fractions.
# Finding a bijection from integers to rationals (ℤ → ℚ) is left as an exercise to the reader.
