1/14일자 TIL

오늘은 코드카타 2개 제출과 함께 1-5강에서 1-7강까지 한번씩 듣고 5강까지 따라해보았다.

두 정수 사이의 합

접근 방법은 알았지만, 힌트를 검색해보고서 int start = min(a, b);와 int end = max(a, b); 를 사용하였다.

#include <string>
#include <vector>

using namespace std;

long long solution(int a, int b) {
    long long answer = 0;
    int start = min(a, b);
    int end = max(a, b);
    for(int i = start; i <= end; i++)
    {
        answer += i;
    }
    return answer;
}

 

콜라츠 추측

조건이 만족될때까지 계속 반복이다보니 반복문 중 While문으로 접근하였고, While(1)과 조건형 While중에 후자를 선택하였다.

#include <string>
#include <vector>

using namespace std;

int solution(int num) {
    long long n = num;
    int answer = 0;
    if (n == 1) return 0;
    while(n != 1 && answer < 500)
    {
        if(n % 2 == 0)
        {
            n = n / 2;
        }
        else
        {
            n = n * 3 + 1;
        }
        answer++;
    }
    if (n == 1) return answer;
    return -1;
    
}

 

그리고 따라해 본 건 1-5강까지였기 때문에 내용 정리는 5강까지.

현재까지 한 진도는 여기에.
