Hi thanks for your help! Could you help me w part 3 of ques 1 too??
Hi sorry to trouble again, I don't understand how you got the last part for q2
Are the numerical values in the first place? Hahaha
Anw for that Qn the first portion is all unique alphabets, 2nd portion is if there's 2 Ls inside
oh I see, I thought only the first case is needed since they said distinct-lettered
Oh I missed that part of the Qn. You're right, distinct lettered means all the alphabets are different.
okay now I understand p&c alr, thanks so much!!!!
