JavaScript 로 알고리즘 풀 때의 input, output 방식

 

 

var input1 = 'a234'
var input2 = '1234'

function solution(s) {
    let len = s.length;   
    let answer = Number(s);    
    if((len === 4 || len === 6) && answer === parseInt(s)) {
        return answer = true; 
    }else {
         return answer = false;
    }
}

console.log('input1: ' + solution(input1))
console.log('input2: ' + solution(input2))

 

 

 

var absolutes = [4,7,12]
var signs = [true, false, true]

function solution(absolutes, signs) {
    let answer = 0;
    for (let i = 0; i < absolutes.length; i++) {
        if(signs[i] === true) {
            answer += absolutes[i]; 
        } else {
            answer -= absolutes[i];
        }
    }
    return answer;
}

console.log('answer: ' + solution(absolutes, signs))
