javaperformanceasciiuppercaselowercase 4 这是一个关于性能的问题。我可以使用以下代码将大写字母转换为小写字母,反之亦然: 从小写字母转换为大写字母: // Uppercase letters. class UpperCase { public static void main(String args[]) { char ch; for (int i = 0; i < 10; i++) { ch = (char...
For example, using ASCII character codes, changing a single bit easily converts text from uppercase to lowercase. The capital letter "A" is represented by the binary value: 0100 0001 The lowercase letter "a" is represented by the binary value: 0110 0001 The difference is the third most ...
print(is_uppercase('A')) 输出:True print(is_uppercase('Z')) 输出:True print(is_uppercase('a')) 输出:False 3、如何使用ASCII编码判断一个字符是否为小写字母? 答:可以使用ord()函数获取字符的ASCII码值,然后判断该值是否在97到122之间(包括97和122)。 def is_lowercase(c): return 97 <= ord(...
