問題描述
　　給定當(dāng)前的時(shí)間仰坦，請(qǐng)用英文的讀法將它讀出來昆烁。
　　時(shí)間用時(shí)h和分m表示，在英文的讀法中缎岗，讀一個(gè)時(shí)間的方法是：
　　如果m為0静尼，則將時(shí)讀出來，然后加上“o'clock”传泊，如3:00讀作“three o'clock”鼠渺。
　　如果m不為0，則將時(shí)讀出來眷细，然后將分讀出來拦盹，如5:30讀作“five thirty”。
　　時(shí)和分的讀法使用的是英文數(shù)字的讀法溪椎，其中0~20讀作：
　　0:zero, 1: one, 2:two, 3:three, 4:four, 5:five, 6:six, 7:seven, 8:eight, 9:nine, 10:ten, 11:eleven, 12:twelve, 13:thirteen, 14:fourteen, 15:fifteen, 16:sixteen, 17:seventeen, 18:eighteen, 19:nineteen, 20:twenty普舆。
　　30讀作thirty，40讀作forty校读，50讀作fifty沼侣。
　　對(duì)于大于20小于60的數(shù)字，首先讀整十的數(shù)歉秫，然后再加上個(gè)位數(shù)蛾洛。如31首先讀30再加1的讀法，讀作“thirty one”。
　　按上面的規(guī)則21:54讀作“twenty one fifty four”轧膘，9:07讀作“nine seven”钞螟，0:15讀作“zero fifteen”。
輸入格式
　　輸入包含兩個(gè)非負(fù)整數(shù)h和m谎碍，表示時(shí)間的時(shí)和分鳞滨。非零的數(shù)字前沒有前導(dǎo)0。h小于24蟆淀，m小于60拯啦。
輸出格式
　　輸出時(shí)間時(shí)刻的英文。
樣例輸入
0 15
樣例輸出
zero fifteen

此題需要注意分鐘的判定扳碍，和十位數(shù)字讀法
