#include<bits/stdc++.h> 
using namespace std;

int main() {
    double s = 2.3;
    double f = 1.9;
    double t = 82.3;
    int v= 0;
    
    for (int i = 0; i <= t / s; i++) {
        double q = t - i * s;
        int d = q / f;
        
        if (i < d) {
            v = i;
        }
    }
    
    cout << v ;

    return 0;
}

这哪错了？
