Scrabble

 

Give a variable number of words, create a program to output the word with the maximum score, based on the following scoring system: 

The score of a word is calculated based on its character values, according to this table: 

e, a, i, o, n, r, t, l, s, u are equal 1 point 

d, g 2 points 

b, c, m, p 3 points 

f, h, v, w, y 4 points 

k 5 points 

j, x 8 points 

q, z 10 points 

 

The max length of a word is 10 letters. 

 

For example:  

input { "This",  "is", "a", "cool" , "Challenge" } 

output : Challenge

Program: 

// get input from user by setting input encoding to utf 8

process.stdin.setEncoding('utf-8');

console.log('Enter a series of words separated by space. Enter 1 to quit.');

process.stdin.on('data', (data) => {

    // data will contain the terms entered by user

    if (data == '1\n') {

        process.exit();

    }

    // Create an array of words entered by user

    const sentenceArray = data.toString().slice(0, -1).toLowerCase().split(' ');

    // here toString converts the data entered by user into string, slice removes the last element i.e \n

    // from the data, toLowerCase is used to convert the data into lower case, and finally split will separate the

    // words by space in add then into array

    const pointsObjectArray = []; // this array will contain all the words with their individual points

    sentenceArray.forEach(element => {

        // here we are further creating another array for each word of sentence 

        const word = element.toString().split('');

        // join will concat the character into words again

        let pointsObject = {word: word.join(''), points: 0};

        let points = 0;

        word.forEach(character => {

            // getPoint is a method which return point of each character based on given table in description

            points += getPoint(character);

        })

        pointsObject.points = points;

        pointsObjectArray.push(pointsObject);

    });

    // method to print the max points word

    printMax(pointsObjectArray);

})

function getPoint(character) {

    // we will use switch case to check for point

    let characterValue;

    switch (character) {

        case 'd':

        case 'g':

            characterValue = 2

            break;

        case /[bcmp]/.test(character):

            characterValue = 3;

            break;

        case /[fhvwy]/.test(character):

            characterValue = 4;

            break;

        case 'k':

            characterValue = 5;

            break;

        case 'j':

        case 'x':

            characterValue = 8;

            break;

        case 'q':

        case 'z':

            characterValue = 10;

            break;

        default:

            characterValue = 1;

            break;

    }

    return characterValue;

}

function printMax(objectsArray) {

    // reduce method will get the object with max points

    const maxPointObject = objectsArray.reduce((prev, current) => (prev.points > current.points) ? prev : current);

    console.log(`The word ${maxPointObject.word} has max points: ${maxPointObject.points}`);
