Two sets $$re created and searched as below. Which search operation is expected to take the longest?

set range $(10)$ set $2=$set$(range(100))$

op$1=1$ in set$1$ # operation $1$

op$2=-1$ in set$1$ # operation $2.$

op$3=1$ in set$2$ # operation $3$

op$4=-1$ in set$2$ # operation $4$

operation $1$

operation $2$

operation $3$

operation $4$

all operations take about the same amount of time
