紅寶石範圍部分

我有一個問題，Ruby代碼：紅寶石範圍部分

def give_me_all_periods(period, paid_periods) 
    # Can you help me? 
end 

period = [1..10] 
paid_periods = [1..2, 5..8] 
give_me_all_periods(period, paid_periods).should == [1...2, 2...5, 5...8, 8...10]

將paid_periods始終期間內或在這是否需要驗證呢？ –

爲什麼它會從'1..2'變爲'1 ... 2'？ –

def give_me_all_periods(period, paid_periods) 
     p = period | paid_periods 
     union = p.inject([]){|u,x| u = u|range_to_arr(x)}.sort 
     ranges =[] 
     union.each_cons(2){|a| ranges << Range.new(a[0],a[1]) } 
     ranges 

end 

def range_to_arr(r) 
     [r.first,r.last] 
end

def give_me_all_periods（period，paid_periods） thresholds =（period + paid_periods）.map {| p | [p.begin，p.end]} .flatten.uniq.sort thresholds.zip（thresholds [1，thresholds.size]）。map {| pair |對[1]？（pair [0] ... pair [1]）：nil} .compact end – arion
