I dnt know if this following logic is correct. Suppose u gave 10options.u got selected In the very 4th option itself.if u rmbr C++ logic Computer checks ur 1st option -u didnt get Computer checks ur 2nd option-u didnt get Same for 3rd option.but computer notices U r eligible for 4th pos n selects u.now Comp hasnt checkd ur next options becz Those 6 r low priority to u compared to ur Favorite 1st 4.now rest 6 r valid unless u Delete it n usually ppl give higher options of Top 4 n delete uncheckd bottom 6.now where Is your problem if u got selectd in 1st option ?u have a choice to delete ur fst option rgt? Please consult wit expert n dnt go entirely by My viewpoint.gl
