1. 村上春樹、河合隼雄に会いにいく

I am a beginner programmer.
I studied Swift by Swift Playgrounds during Sep 14 → Nov 17 in 2016. (Swift is my almost first programming language)

Result : 『Learn to Code2』 Arrays, Another Way to Create an Array → World Creation.

A long journey of Swift Playgrounds Study is over🎉
I was struggling with Arrays area. It was hard for me to understand.

Result : 『Learn to Code2』 Arrays, Randomized Lands.

I can’t solved this task, “Randomized Lands”.

So I did that referring to this Youtube video(Randomized Lands — Swift Playgrounds). Thanks.
However still I have no idea why…
