Created September 4, 2014 14:43
Suppose I have the following Array of tuples [ ['a',1], ['b',2], ['c','3' ] How can I convert this to a Hash? { 'a' => 1, 'b' => 2, 'c' => 3}?
a = [ ['a',1], ['b',2], ['c',3] ]
h={}
a.flatten!.each_with_index {|el, i| i % 2 == 0 ? h[el]=a[i+1] : () }
h
# => {"a"=>1, "b"=>2, "c"=>3}

Задача про непарные числа в массиве
a = [4,1,1,2,2,3,3,3,2,2,5,5,5,5]
el = a.pop
while el do # O(N)
# в массиве осталось нечетное число чисел равных el
if a.find_all {|m| m == el}.size % 2 != 0 # O(N2)
a.delete_if {|m| m == el} # O(N3) значит вместе с el их было четное число, значит это не то что мы ищем
else # если осталось четное число или 0, то изначально было нечетное, это то что мы ищем
puts "Непарный элемент: #{el}"
break
