根据边长判断

#include <iostream>
using namespace std;

void func(int a, int b, int c) {
    int min = a < b ? a : b;
    min = min < c ? min : c;
    int max = a > b ? a : b;
    max = max > c ? max : c;
    int mid = a + b + c - min - max;
    if (min * min + mid * mid == max * max) {
        cout << "直角三角形" << endl;
    }
    if (min * min + mid * mid < max * max) {
        cout << "钝角三角形" << endl;
    }
    if (min * min + mid * mid > max * max) {
        cout << "锐角三角形" << endl;
    }
}

int main() {
    int a, b, c;
    while (cin >> a >> b >> c) {
        func(a, b, c);
    }
    return 0;
}
// 64 位输出请用 printf("%lld")
