以下是Java代码实现,可以通过LeetCode的Java环境进行测试:
public class Car {
private int x;
private int y;
private int velocity;
private int direction;
public Car(int x, int y, int velocity, int direction) {
this.x = x;
this.y = y;
this.velocity = velocity;
this.direction = direction;
}
public void move(int changeDirection, int changeVelocity) {
if (velocity == 0) {
return;
}
// 更新速度
velocity += changeVelocity;
if (velocity < 0) {
velocity = 0;
} else if (velocity > 20) {
velocity = 20;
}
// 更新方向
direction = (direction + changeDirection) % 4;
if (direction == 0) {
direction = 4;
}
// 根据方向和速度更新位置
switch (direction) {
case 1:
x += velocity;
break;
case 2:
y -= velocity;
break;
case 3:
x -= velocity;
break;
case 4:
y += velocity;
break;
}
}
public String getPosition() {
return x + "," + y;
}
}
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int x = scanner.nextInt();
int y = scanner.nextInt();
int velocity = scanner.nextInt();
int direction = scanner.nextInt();
int n = scanner.nextInt();
Car car = new Car(x, y, velocity, direction);
for (int i = 0; i < n; i++) {
int changeDirection = scanner.nextInt();
int changeVelocity = scanner.nextInt();
car.move(changeDirection, changeVelocity);
}
System.out.println(car.getPosition());
}
}
