王老师 题目 1892.转弯 #include <iostream> #include <cstring> #include <algorithm> using namespace std; int x[60], y[60]; int main() { int n, m, r, t, s = 0, u = 0; cin >> n >> m >> r >> t; for (int i = 0; i < r; i++) { cin >> x[i] >> y[i]; } for (int i = 0; i < r; i++) { if (x[i] - x[i + 1] > t) { s += t * t * r; } else { if (x[i] > y[i]) { u += x[i] - y[i]; } else { u += y[i] - x[i]; } if (u >= r) { s -= 1; } } } cout << s; } 为什么错？？？
