[백준_javascript] 입출력과 사칙연산(11382)

#11382 (꼬마 정민)

const fs = require('fs');
const file = process.platform === 'linux' ? '/dev/stdin' : __dirname+'/input.txt';

const [a,b,c] = fs.readFileSync(file).toString().split(' ').map(Number);

console.log(a+b+c);

 

** reduce함수 활용

const fs = require('fs');
const file = process.platform === 'linux' ? '/dev/stdin' : __dirname+'/input.txt';

const input  = fs.readFileSync(file).toString().trim().split(' ').map(Number);
const answer = input.reduce((a,b)=>a+b)
console.log(answer);

 

** 조금 더 간결하게!

const fs = require('fs');
const file = process.platform === 'linux' ? '/dev/stdin' : __dirname+'/input.txt';

const input2  = fs.readFileSync(file).toString().trim().split(' ').map(Number).reduce((a,b)=>a+b);
console.log(input2);
