1st arrange the words in ascending order
so, it will be AEHMNT
now, we need 24th words so we can get it swapping
the last 4 word with each other: 4!
"AE" is const and arrange last 4 words in ascend order: TNMH
24th word: AETNMH
now to get 28th we need to make "AH" as const and arranging last 3 words
ie: "AH"EMNT , arrange last 3 words
25 word: AHEMNT
26: AHEMTN
27: AHENMT
28: AHENTM

now decuct the rest

the first word is AEHMNT
take AE as constant and keep on changing the position of rest of the four.so,4!=24
the 24th word is AETNMH
28th= AHENTM
48th= AHTNME
50th= AMEHTN

HEMANT
WE WILL GET 24 WORD BY COMBINATION OF LAST 4 ALPHABET MEANS 4!
AS WE KNOW IN DICTIONARY WORDS ARE PLACED IN ORDER A,B,C......
SO THE 24 TH WORD WILL BE "HETNMA".
IN CASE OF 28 TH WORD WE WILL DONE THE COMBINATION OF LAST THREE ALPHABETS OF
"HETNMA" SO IT WILL GIVE 3! OR 6 COMBINATION. THE COMBINATION ARE ACCORDING
TO DICTIONARY 1.AMN,2.ANM,3.MAN,4.MNA,5.NAM,6.NMA
SO 28 TH WORD WILL BE "HET" THEN 4TH COMBINATION MEANS "HETMNA".
IN CASE OF 48 TH WORD WE WILL DONE COMBINATION OF LAST 5 ALPHABETS MEANS 5! OR 120.
IN THIS CASE WE WILL MAKE 1ST ALPHABETS CONSTANT AND COMBINATION OF OTHER 4 SO WE WILL GET 24 COMBINATION FOR EACH THAT MEANS WE WILL GET 48 TH WORD ACCORDING TO DICTIONARY IS "ETNMA" SO 48 TH WORD WILL BE "HETNMA". AND 50TH IS "HETNMA"
