def solution(str1, str2):
    answer = 2
    if str2 in str1:
        answer = 1
    return answer

#include <string>
#include <vector>

using namespace std;

int solution(string str1, string str2) {
    int answer = 0;
    int index = str1.find(str2);
    (index == -1) ? answer = 2 : answer = 1 ;
    return answer;
}

- 이렇게 해도 됨

#include <string>

using namespace std;

int solution(string str1, string str2) {
    return str1.find(str2) == -1 ? 2 : 1;
}
