用分号统计字符串中的字符组

def count_char_groups(string):
    char_groups = {}
    for char in string:
        if char in char_groups:
            char_groups[char] += 1
        else:
            char_groups[char] = 1
    
    result = ""
    for char, count in char_groups.items():
        result += f"{char}:{count};"
    
    return result

# 示例用法
string = "abcaabbbcc"
result = count_char_groups(string)
print(result)
