如何获取具有相同模式的所有字符串

def get_matching_strings(pattern, target):
    pattern_units = list(pattern)
    target_units = list(target)
    matching_strings = []

    def match(pattern_units, target_units, current_string):
        if not pattern_units and not target_units:
            matching_strings.append(current_string)
            return

        if not pattern_units or not target_units:
            return

        pattern_unit = pattern_units[0]
        remaining_pattern_units = pattern_units[1:]
        target_unit = target_units[0]
        remaining_target_units = target_units[1:]

        if pattern_unit in current_string:
            # If the pattern unit already exists in the current string, continue matching with the next pattern unit
            match(remaining_pattern_units, target_units, current_string)
        else:
            # Try to match the pattern unit with the target unit
            match(remaining_pattern_units, remaining_target_units, current_string + target_unit)

    match(pattern_units, target_units, "")

    return matching_strings

# Example usage
pattern = "ABBA"
target = "redbluebluered"
result = get_matching_strings(pattern, target)
print(result)
