nested array

Question

inside the following array : [5,[9,4,6],[8]], how can we obtain the output of 5?

Answer 1

the array is structured as following

0 1 2
0 5 N N
1 9 4 6
2 8 N N

where N is an uninitialized memory
so row 0 and column 0 will have the value 5
so if the array name is ar, then arr[0][0] will return the value 5

Answer 2

Good answer, Burey !

Answer 3

It was a good question 😬

Answer 4

b = [5,[9,4,6],[8]]
p b[0] #=> 5
p b[1] #=> [9,4,6]
p b[2] #=> [8]
p b[2][0] #=> 8

Answer 5

arr = [5,[9,4,6],[8]]
puts arr[0]
