consonantValue.js

// Given a lowercase string that has alphabetic characters only and no spaces, return the highest value of consonant substrings.Consonants are any letters of the alpahabet except "aeiou".

// We shall assign the following values: a = 1, b = 2, c = 3, ....z = 26.

// For example, for the word "zodiacs", let's cross out the vowels. We get: "z o d ia cs"

// --The consonant substrings are: "z", "d" and "cs" and the values are z = 26, d = 4 and cs = 3 + 19 = 22. The highest is 26.
// solve("zodiacs") = 26

// For the word "strength", solve("strength") = 57
// --The consonant substrings are: "str" and "ngth" with values "str" = 19 + 20 + 18 = 57 and "ngth" = 14 + 7 + 20 + 8 = 49. The highest is 57
