what does "iterating over consecutive elements" mean and show example in ruby

"Iterating over consecutive elements" means going through a collection or sequence of elements in a consecutive or sequential manner, processing each element one by one. In Ruby, there are several ways to iterate over consecutive elements, including using loops and enumerable methods.

One common way to iterate over consecutive elements in Ruby is using a for loop or a range. Here's an example:

main.rb
numbers = [1, 2, 3, 4, 5]

for i in 0...numbers.length
  puts numbers[i]
end
77 chars
6 lines

This code snippet iterates over each element in the numbers array by using a for loop and printing each element using the index i. The 0...numbers.length range is used to specify the indices of the array.

Another way is using the each method, which is available for arrays and other enumerable objects:

main.rb
numbers = [1, 2, 3, 4, 5]

numbers.each do |number|
  puts number
end
70 chars
6 lines

In this example, the each method is called on the numbers array, and for each iteration, the current element is assigned to the variable number. The block of code inside the do...end is executed for each element in the array, printing the value of number.

These are just a couple of examples of iterating over consecutive elements in Ruby. There are many more ways to achieve the same result, depending on the specific requirements of your code."
