Table: Samples
\n+----------------+---------+\n| Column Name | Type | \n+----------------+---------+\n| sample_id | int |\n| dna_sequence | varchar |\n| species | varchar |\n+----------------+---------+\nsample_id is the unique key for this table.\nEach row contains a DNA sequence represented as a string of characters (A, T, G, C) and the species it was collected from.\n\n\n
Biologists are studying basic patterns in DNA sequences. Write a solution to identify sample_id with the following patterns:
3 consecutive G (like GGG or GGGG)Return the result table ordered by sample_id in ascending order.
\n\nThe result format is in the following example.

Example:
\n\nInput:
\n\nSamples table:
\n\n\n+-----------+------------------+-----------+\n| sample_id | dna_sequence | species |\n+-----------+------------------+-----------+\n| 1 | ATGCTAGCTAGCTAA | Human |\n| 2 | GGGTCAATCATC | Human |\n| 3 | ATATATCGTAGCTA | Human |\n| 4 | ATGGGGTCATCATAA | Mouse |\n| 5 | TCAGTCAGTCAG | Mouse |\n| 6 | ATATCGCGCTAG | Zebrafish |\n| 7 | CGTATGCGTCGTA | Zebrafish |\n+-----------+------------------+-----------+\n\n\n

Explanation:
\n\nNote:
\n\n表：Samples
\n+----------------+---------+\n| Column Name | Type | \n+----------------+---------+\n| sample_id | int |\n| dna_sequence | varchar |\n| species | varchar |\n+----------------+---------+\nsample_id 是这张表的唯一主键。\n每一行包含一个 DNA 序列以一个字符（A，T，G，C）组成的字符串表示以及它所采集自的物种。\n\n\n
生物学家正在研究 DNA 序列中的基本模式。编写一个解决方案以识别具有以下模式的 sample_id：
3 个连续 G 的序列（如 GGG 或 GGGG）返回结果表以 sample_id 升序 排序。
\n\n结果格式如下所示。
