The 22th Project Euler problem - Names Scores - is stated as follows.
Using names.txt, a 46K text file containing over five-thousand first names, begin by sorting it into alphabetical order. Then working out the alphabetical value for each name, multiply this value by its alphabetical position in the list to obtain a name score.
For example, when the list is sorted into alphabetical order, COLIN, which is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So, COLIN would obtain a score of 938 × 53 = 49714.
What is the total of all the name scores in the file? — Project Euler, Names Scores, Problem 22
const fs = require('fs'); // Read the textfile into a string. const names = fs.readFileSync('p022_names.txt', 'utf8') // Split the string on every comma and remove the quotes .split(',').map(name => name.replace(/"/g, '')) // Sort the names. .sort(); // Get the alphabetical value by adding the chars position in // the alphabet. A = Char Code 65 = Alphabet Position 1. const getAlphabeticalValue = name => name.split('') .reduce((memo, item) => memo + item.charCodeAt(0) - 64, 0); const result = names.reduce((memo, item, index) => memo + getAlphabeticalValue(item) * (index + 1), 0);
