JOI2019/2020 一次予選第三回 A問題,B問題の解き方

Posted at

JOI2019/2020の一次予選第三回、お疲れさまでした.
コンテスト中ではB問題のみ解けました.
解説が出ているから公開していいはず。
使用言語 : C++,Python3

#A問題
qiita_joia.png
#解法
X < L
の時、Lを出力.

L <= X <= R
の時、Xを出力.

R < X
の時、Rを出力.

#コード

A.cpp
#include <iostream>

using namespace std;

int main(){
    int X;
    int L;
    int R;
    cin >> X >> L >> R;
    if(X < L){
        cout << L << endl;
    }
    else if(L <= X and X <= R){
        cout << X << endl;
    }
    else if(R < X){
        cout << R << endl;
    }
}

以上.

#B問題

#解法
Python3のreplace関数を使って"joi" という文字列を"JOI"に置き換える.

#コード

B.py
N, S = int(input())
print(S.replace('joi', 'JOI'))

以上.

#感想
C問題もだけど、コンテスト中にA問題を解けなかったのが悔しいです...。
