array <<
hash having a key keys[0] == hash.keys[0] then you need to increase its value by +1.

Answer 1

Wrote in haste

array = [ { 1 => 5, 23 => 1}, { 2 => 6, 22 => 2} ]
hash = { 1 => 5, 23 => 1}
array = array.map do |x|
  first_key = x.keys[0]
  x[first_key] = x[first_key] + 1 if first_key == hash.keys[0]
  x
end
