The letter value of a letter is its position in the alphabet starting from 0 (i.e. 'a' -> 0
, 'b' -> 1
, 'c' -> 2
, etc.).
The numerical value of some string of lowercase English letters s
is the concatenation of the letter values of each letter in s
, which is then converted into an integer.
- For example, if
s = "acb"
, we concatenate each letter's letter value, resulting in"021"
. After converting it, we get21
.
You are given three strings firstWord
, secondWord
, and targetWord
, each consisting of lowercase English letters 'a'
through 'j'
inclusive.
