需警慎！！！

直接上代码

#include<bits/stdc++.h>
using namespace std;
char toLower(char c) {
    if (c >= 'A' && c <= 'Z') {
        return c + 32;
    }
    return c;
}
int main() {
    string s, s1;
    getline(cin, s);
    getline(cin, s1);
    int l = s.size(), l1 = s1.size();
    int minLen = min(l, l1);
    int result = 0;
    for(int i = 0; i < minLen; i++) {
        char c1 = toLower(s[i]);
        char c2 = toLower(s1[i]);
        
        if (c1 > c2) {
            cout << ">";
            result = 1;
            break;
        } else if (c1 < c2) {
            cout << "<";
            result = -1;
            break;
        }
    }
    if (result == 0) {
        if (l > l1) {
            cout << ">";
        } else if (l < l1) {
            cout << "<";
        } else {
            cout << "=";
        }
    }
    return 0;
}
