📝 Question Description

1、双重循环，loop_2中的任何节点均无法获取遍历中的元素，只能获取索引。
2、loop_1可以同时获取遍历中的元素和索引
3、在实际的业务应用中有获取loop_2中元素值的需求，例如需要二重循环遍历二维数组[[1,2,3],[4,5,6]]，当【元素值=5】时退出循环。

📝Question Description

1. Double loop, any node in loop_2 cannot obtain the elements in the traversal, but can only obtain the index.
2. loop_1 can obtain the elements and indexes in the traversal at the same time
3. In actual business applications, there is a need to obtain the element value in loop_2. For example, it is necessary to traverse the two-dimensional array [[1,2,3],[4,5,6]] in a double loop, and exit the loop when [element value = 5].
