My name is saksham goyal from india. we could code like this:

1st letter a as 3rd fibonacci term 1
2nd letter b as 4th fibonacci term 2

for spaces we can use 0

for very long number such as 75025 (26th for z) we can use 7+5+0+2+5 = 19

in case for same sums like 75025 and 2584(18th) we can either right full number or write 19 to base 18 or to base 26(i.e. in sub script)

in case you like this..............plz email me on
