for pt 2 what speciically are we supposed to do ?

and for pt 3 4.45 could anyone help me with that , i get a total of 42 combinations , but the teachers is only asking for 21

yeah , i figured , but im clueless in how to change my program so it won't display the same combinations .

i could get it to not display numbers like 11 22 33 44 55 66 77 , but not the same combinations like you pointed out.
