关于 /2 和 >>1的除2问题

起因是看到了题解里的一串代码

int mid = ((right - left) >> 1) + left;

然后这种右移除法我没看懂,因为我脑子里还有一种写法:

(left + (right - left) / 2);

但运行下来,这两种是有差别的,当 left 和 right 之间差值非常大,那么/2的写法将会比 left 要打而不一定小于 left + right ,这可能导致中间索引溢出到右边,而>>1的写法,可以保证中间索引不会溢出,因为 >>1 操作相当于除以2,然后加上left ,中间索引一定小于left+right

<think>根据错误信息,有两个主要问题1.在pom.xml的第122行附近,存在一个文本“极”,导致XML解析失败(expectedSTART_TAGorEND_TAGnotTEXT)。2.在依赖项cn.jpush.api极:jpush-client中,groupId'cn.jpush.api极'包含非法字符('极'),不符合Maven的groupId命名规范。解决方案:1.删所有非法的文本字符(例如“极”),这些字符可能是误输入的。2.确保groupId、artifactId等只包含合法的字符(字母、数字、点、连字符等)。具体需要检查的位置:-122行附近:在依赖项`org.springframework:spring-websocket`的声明中,有一个文本“极”在`<groupId>`标签之前。-220行:在依赖项`cn.jpush.api极:jpush-client`中,groupId为`cn.jpush.api极`,应删“极”字。修改后的pom.xml需要确保所有标签都是正确闭合的,且没有非法字符。以下是修复后的pom.xml(注意:我已经删了所有出现的“极”字,并修正了这两个依赖项):</think>### 修复后的完整 POM.xml 文件 错误分析: 1. XML 格式错误:存在非法字符 `极` 出现在标签内部 2. GroupId 格式错误:`cn.jpush.api极` 包含非法字符 `极` 3. XML 声明错误:`xmlns:xsi` 值中包含非法字符 `极` 以下是修复后的完整 POM.xml: ```xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ``` 2. **GroupId 修复**: ```xml <!-- 修复前 --> <groupId>cn.jpush.api极</groupId> <!-- 修复后 --> <groupId>cn.jpush.api</groupId> ``` 3. **非法字符移**: ```xml <!--所有位置出现的 "极" 字符 --> <!-- 例如: --> <dependency> 极<groupId>org.springframework</groupId> <!--行首的 "极" --> </dependency> ``` 4. **标签内容清理**: ```xml <!-- 修复前 --> <artifactId>c3极p0</artifactId> <!-- 修复后 --> <artifactId>c3p0</artifactId> ``` ### 验证修复 执行以下命令验证修复: ```bash mvn clean package -U ``` ### 预防 XML 格式错误的建议 1. **使用 XML 验证工具**: ```bash xmllint --noout pom.xml ``` 2. **IDE 辅助检查**: -IntelliJ IDEA 或 Eclipse 中打开 POM.xml - 使用内置的 XML 验证功能 3. **编码规范**: ```xml <!-- 避免在标签内容中使用特殊字符 --> <!-- 正确 --> <version>1.0.0</version> <!-- 错误 --> <version>1.0.0极</version> ``` ###
