Sample
```ruby
def max_repetition(r1, r2)
if r1[:repetitions] > r2[:repetitions] || (r1[:repetitions] == r2[:repetitions] && r1[:number] > r2[:number])
r1
else
r2
end
end

def most_repeated(array)
if array.empty?
return {number: nil, repetitions: nil}
end

current = {number: array[0], repetitions: 1}
max = current

array[1..-1].each do |number|
if current[:number] == number
current[:repetitions] += 1
else
max = max_repetition(current, max)
current = {number: number, repetitions: 1}
end
end

max_repetition(current, max)
end
```
