如何替换文本区域中的最后一个字符？

text = "Hello, World!"
new_text = text.replace("World!", "Universe!")
print(new_text)

import re

text = "Hello, World!"
new_text = re.sub("World!", "Universe!", text)
print(new_text)

const text = "Hello, World!";
const newText = text.replace("World!", "Universe!");
console.log(newText);

const text = "Hello, World!";
const newText = text.replace(/World!/g, "Universe!");
console.log(newText);

String text = "Hello, World!";
String newText = text.replace("World!", "Universe!");
System.out.println(newText);

String text = "Hello, World!";
String newText = text.replaceAll("World!", "Universe!");
System.out.println(newText);

#include <iostream>
#include <string>

int main() {
    std::string text = "Hello, World!";
    std::string newText = text.replace("World!", "Universe!");
    std::cout << newText << std::endl;
    return 0;
}

#include <iostream>
#include <string>
#include <regex>

int main() {
    std::string text = "Hello, World!";
    std::string newText = std::regex_replace(text, std::regex(R"(\W)World\W"), "Universe!");
    std::cout << newText << std::endl;
    return 0;
}
