풀이

간단한 배열문제이지만 생각할 것이 많았다.

function solution(answers) {
    var answer = [];
    const firstChild = [1,2,3,4,5]
    const secondChild = [2,1,2,3,2,4,2,5]
    const thirdChild = [3,3,1,1,2,2,4,4,5,5]
    let score = [0,0,0]
    
    for(let i = 0; i < answers.length; i ++){
        if(answers[i] == firstChild[i %firstChild.length]) score[0]++;
        if(answers[i] == secondChild[i % secondChild.length]) score[1]++;
        if(answers[i] == thirdChild[i % thirdChild.length]) score[2]++;
    }
   const winner = Math.max(...score)
   
   for(let i=0;i<score.length;i++){
       if(winner==score[i]){
           console.log(answer)
           answer.push(i+1)
       }
   }
    return answer;
}
