Exercise 4.72: Why do disjoin and

stream-flatmap interleave the streams rather than simply append them?

Give examples that illustrate why interleaving works better. (Hint: Why did we

use interleave in 3.5.3?)

练习 4.72：为什么 disjoin 和 stream-flatmap 采用交错方式而非简单拼接各流？请举例说明交错方式为何效果更好。（提示：我们为什么在 3.5.3 中使用了 interleave？）
