给定一个字符串，使用c++删除重复的连续字符

#include <iostream>
#include <string>

std::string removeDuplicates(const std::string& str) {
    std::string result;
    
    for (int i = 0; i < str.length(); i++) {
        // 判断当前字符是否与下一个字符相同
        if (str[i] != str[i+1]) {
            result += str[i];  // 若不相同则将字符添加到结果字符串中
        }
    }
    
    return result;
}

int main() {
    std::string input = "aaabbbcccdddeeefffggg";
    std::string output = removeDuplicates(input);
    
    std::cout << "Original string: " << input << std::endl;
    std::cout << "String after removing duplicates: " << output << std::endl;
    
    return 0;
}

Original string: aaabbbcccdddeeefffggg
String after removing duplicates: abcdefg
