A. Petya and Strings

原题传送门

题目描述

给你两个字符串按字典序进行比较，不区分大小写

分析

先将字符串格式化，即将字符串中所有字符全部变为小写，再进行比较

代码

#include <bits/stdc++.h>
using namespace std;const int maxn = 1e2 + 10;string s1, s2;void init (string &s) {for (int i = 0; i < s.length(); i++) s[i] = tolower(s[i]);
}int main() {ios::sync_with_stdio(false);cin >> s1 >> s2;init (s1);init (s2);if (s1 < s2) cout << "-1" << endl;if (s1 == s2) cout << "0" << endl;if (s1 > s2) cout << "1" << endl;return 0;
}
