In an array without using loops, how to find which element in the array satisfies certain condition
The question is similar to this: In an array without using loops, how to find which element in the array satisfies certain condition
However, I want to know how to do it without using loops.
A:
You can get all indices that satisfy a condition:
[0...10].select{|i| i % 2 == 0} #=> [2, 4, 6, 8]
Now you can take a look at the desired index and modify the condition:
[1,3,5,7,9,11].select{|i| i % 2 == 0}[2].first #=> 1
Finally you can use that in an array slice
[1,3,5,7,9,11].slice(2) #=> [3, 5, 7, 9]
Or you can use a map operation:
[1,3,5,7,9,11].map{|i| i % 2 == 0}[2].first #=> 3
Both methods avoid enumerating all elements and save a lot of time.
