What word does this string result into?
The ; sign marks separation between letters.
I think the answer is
Using the usual alphabet-to-numbers conversion (a=1, b=2, and so on).
I get HELLO convert character to number with a starting as 1 and increment by 1 i - a gets you h 19[i]-1[a] = 18[h] 2b + a gets you 2(2[b]) + 1[a] = 5[e] 2f gets you 2(6[f]) = 12[l] e + e + e gets you 5[e] + 5[e] + 5[e] = 15[o]
