yeah i have no clue
lol hahah it hurts my brain lol
I got Starting with letter A, and arranging the other four letters, there are 4! = 24 words. These are the first 24 words. Then starting with G, and arranging A, A, I and N in different ways, there are 4! 12 2!1!1! = words. Next the 37 th word starts with I. There are again 12 words starting with I. This accounts up to the 48 th word. The 49 th word is NAAGI. is it correct ?
?
whaaaaaaaat? lolol
Thank you madam
Nope. You've got two A's, so there are 24*2 starting with A. It says "all permutations", not "all unique permutations". The 49th permutation is the first one that starts with G: GAAIN!
