Question

In Ruby, given an array in one of the following forms...

[apple, 1, banana, 2]
[[apple, 1], [banana, 2]]

...what is the best way to convert

Answer 1

Not sure if it's the best way, but this works:

a = ["apple", 1, "banana", 2]
m1 = {}
for x in (a.length / 2).times
  m1[a[x*2]] = a[x*2 + 1]
end

b = [["apple", 1], ["banana", 2]]
m2 = {}
for x,y in b
  m2[x] = y
end
