Problem Description

정수 n이 매개변수로 주어질 때 n의 각 자리 숫자의 합을 return하도록 solution 함수를 완성해주세요

 

Restrictions

• 0 ≤ n ≤ 1,000,000

 

Input/Output Example

• 입출력 예 #1 1 + 2 + 3 + 4 = 10을 return합니다.

My solution

function solution(str1, str2) {
    return str1.includes(str2) ? 1 : 2
}

 

Another solutions

function solution(str1, str2) {
    return str1.split(str2).length > 1 ? 1 : 2
}
