Thank you untuk postnya, membantu sekali untuk menjelaskan tentang materi ini.

Btw, izin tanya, kenapa stdout-nya HARUS diset -1 ya dan dapet dari mana ide stdout nya -1?

Thankks!

Translation: Thank you for the post, I find it really insightful for explaining the material.

By the way, I wanna ask about the stdout value. Why the stdout's value was set to -1 and how did you think the value must be set to -1?

Thankks!
