Problem 1030A In Search of an Easy Problem (Codeforces 800)

协调者在准备比赛时尽力让第一个问题尽可能简单。如果询问的n个人中有至少一个人认为问题困难,就会更换问题。输入n(1≤n≤100)和n个0或1的整数,表示每个人的意见。如果所有人的回答都是0,则输出"EASY",否则输出"HARD"。

In Search of an Easy Problem

When preparing a tournament, Codeforces coordinators try treir best to make the first problem as easy as possible. This time the coordinator had chosen some problem and asked nnn people about their opinions. Each person answered whether this problem is easy or hard.

If at least one of these nnn people has answered that the problem is hard, the coordinator decides to change the problem. For the given responses, check if the problem is easy enough.

Input

The first line contains a single integer nnn (1≤n≤1001≤n≤1001n100) — the number of people who were asked to give their opinions.

The second line contains nnn integers, each integer is either 000 or 111. If iii-th integer is 000, then iii-th person thinks that the problem is easy; if it is 111, then iii-th person thinks that the problem is hard.

Output

Print one word: “EASY” if the problem is easy according to all responses, or “HARD” if there is at least one person who thinks the problem is hard.

You may print every letter in any register: “EASY”, “easy”, “EaSY” and “eAsY” all will be processed correctly.

Examples

input
3
0 0 1
output
HARD
input
1
0
output
EASY

Simplified Question 题目大意

输入若干数字, 全部是000输出EASY, 有一个111就输出HARD.

Accepted Answer AC 代码

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

int main(){
	int n, a; cin>>n;
	while (n--){
		cin>>a;
		if (a==1){
			cout<<"Hard"; return 0; //这里要return 0 结束程序
		}
	}
	cout<<"Easy";
	return 0;
}

<think>我们正在分析系统日志中的几个错误:OMG_MultiGesture报错(invalid pointerIndex)、sensors-hal报错(qmi connection closed)、KeymasterUtils报错(IKMHal_sendCmd failed with rsp_header->status: -28)。我们将逐一分析每个错误,并尝试给出可能的解决方案。 ### 1. OMG_MultiGesture 报错:invalid pointerIndex 这个错误通常与触摸事件处理有关,尤其是在多点触控手势识别过程中。当系统尝试访问一个不存在的触摸点索引(pointerIndex)时,就会抛出此错误。 **可能原因:** - 触摸事件传递过程中,某个触摸点的索引超出了有效范围。 - 手势识别库在处理触摸事件时,没有正确维护触摸点状态。 - 驱动或硬件问题导致触摸事件数据异常。 **解决方案:** 1. **检查应用代码:** 如果是开发自己的应用,确保在处理触摸事件(如`MotionEvent`)时,使用正确的`pointerIndex`。例如,在遍历触摸点之前,先检查`getPointerCount()`,并确保索引在`0`到`getPointerCount()-1`之间。 ```java for (int i = 0; i < event.getPointerCount(); i++) { float x = event.getX(i); // 确保i在有效范围内 } ``` 2. **更新系统或驱动:** 如果错误来自系统层,可能是系统手势识别模块的bug。检查是否有系统更新可用,或者尝试更新触摸屏驱动。 3. **检查第三方应用:** 如果错误在特定应用使用时出现,尝试卸载该应用或等待其更新。 ### 2. sensors-hal 报错:qmi connection closed 这个错误与传感器硬件抽象层(HAL)和QMI(Qualcomm Modem Interface)通信有关。QMI是高通平台用于处理器与调制解调器之间通信的协议。当sensors-hal尝试通过QMI与调制解调器通信时,连接已关闭。 **可能原因:** - 调制解调器(Modem)崩溃或重启。 - QMI服务异常终止。 - 传感器HAL层与QMI接口的兼容性问题。 **解决方案:** 1. **重启设备:** 临时解决方法是重启设备,以重新建立QMI连接。 2. **更新Modem固件:** 检查是否有可用的基带固件更新,更新到最新版本。 3. **检查系统日志:** 使用`adb logcat`或类似工具查看完整的日志,寻找与调制解调器或QMI相关的其他错误,以确定根本原因。 4. **重置网络设置:** 如果问题与网络相关,尝试在设置中重置网络设置(注意:会清除Wi-Fi密码等)。 5. **联系设备厂商:** 如果是设备特定问题,可能需要厂商提供补丁。 ### 3. KeymasterUtils 报错:IKMHal_sendCmd failed with rsp_header->status: -28 这个错误发生在Keymaster硬件抽象层(HAL)发送命令时失败,返回状态码-28。Keymaster是Android中用于密钥管理的安全模块。 **错误分析:** - 状态码-28通常表示`KM_ERROR_INVALID_OPERATION_HANDLE`,即操作句柄无效。这可能是由于尝试使用一个已经过期或无效的句柄执行密钥操作。 - 其他可能原因包括Keymaster TA(Trusted Application)崩溃、HAL与TA通信失败等。 **解决方案:** 1. **清除Keystore数据:** 尝试清除Keystore系统应用的数据(注意:这将删除所有应用密钥,需要重新生成)。 - 进入设置 > 应用 > 显示系统应用 > 查找“Keystore” > 存储 > 清除数据。 - 重启设备。 2. **更新系统和安全补丁:** 确保系统更新到最新版本,特别是安全补丁,因为Keymaster相关问题通常通过安全更新修复。 3. **检查密钥操作代码:** 如果是应用开发,确保在使用Keymaster时正确管理操作句柄。例如,确保每次`begin`操作后都调用`finish`或`abort`,避免句柄泄漏。 ```java try { KeymasterOperation operation = keyStore.begin(operationSpec); // 使用操作... operation.finish(); // 确保完成操作 } catch (...) { // 异常处理 } ``` 4. **恢复出厂设置:** 如果问题持续,考虑备份数据后进行恢复出厂设置,以排除软件冲突。 5. **联系设备厂商:** 如果设备在保修期内,且问题在恢复出厂设置后仍存在,可能是硬件问题,需要联系厂商。 ### 通用建议 - **收集完整日志:** 使用`adb logcat -b all > log.txt`收集完整日志,搜索相关关键字(如`OMG_MultiGesture`、`sensors-hal`、`KeymasterUtils`)以获取更多上下文。 - **检查系统更新:** 确保设备系统和安全补丁是最新的。 - **安全模式:** 重启进入安全模式,以排除第三方应用干扰。 如果以上方法不能解决问题,可能需要更深入的调试,例如获取内核日志(`dmesg`)或联系设备制造商获取支持。 §§相关问题§§ 1. 如何获取Android设备的完整系统日志? 2. 在Android开发中如何避免触摸事件处理中的invalid pointerIndex错误? 3.
