Помогите написать программу С++

 #include <iostream> 
using namespace std; 
int* locale_min(int* box, const size_t n) { 
    if (!box || n < 3) return nullptr; 
    int* pos = nullptr; 
    auto a = box[0]; 
    auto b = box[1]; 
    for (size_t i = 2; i < n; ++i) { 
        auto c = box[i]; 
        if (b < a && b < c) { 
            if (pos && *pos > b) pos = &box[i - 1]; 
            else pos = &box[i - 1]; 
        } 
        a = b; 
        b = c; 
    } 
    return pos; 
} 
int main() { 
    cout << "N: "; 
    int n; 
    cin >> n; 
    auto box = new int[n]; 
    cout << "Elements: "; 
    for (size_t i = 0; i < n; ++i) cin >> box[i]; 
    auto pos = locale_min(box, n); 
    if (pos == nullptr) puts("Not found!"); 
    else cout << "Local min: " << *pos << '\n'; 
    delete[] box; 
}
