題目內(nèi)容：
無線電臺的RS制信號報(bào)告是由三兩個部分組成的：
R(Readability) 信號可辨度即清晰度.
S(Strength) 信號強(qiáng)度即大小.
其中R位于報(bào)告第一位，共分5級，用1—5數(shù)字表示.
1---Unreadable
2---Barely readable, occasional words distinguishable
3---Readable with considerable difficulty
4---Readable with practically no difficulty
5---Perfectly readable
報(bào)告第二位是S，共分九個級別，用1—9中的一位數(shù)字表示
1---Faint signals, barely perceptible
2---Very weak signals
3---Weak signals
4---Fair signals
5---Fairly good signals
6---Good signals
7---Moderately strong signals
8---Strong signals
9---Extremely strong signals
現(xiàn)在，你的程序要讀入一個信號報(bào)告的數(shù)字，然后輸出對應(yīng)的含義。如讀到59，則輸出：
Extremely strong signals, perfectly readable.

輸入格式:
一個整數(shù)，信號報(bào)告。整數(shù)的十位部分表示可辨度，個位部分表示強(qiáng)度。輸入的整數(shù)范圍是[11,59]內(nèi)有效的數(shù)字，這個范圍外的數(shù)字不可能出現(xiàn)在測試數(shù)據(jù)中。

輸出格式：
一句話，表示這個信號報(bào)告的意義。按照題目中的文字，先輸出表示強(qiáng)度的文字，跟上逗號和空格，然后是表示可辨度的文字，跟上句號。注意可辨度的句子的第一個字母是小寫的。注意這里的標(biāo)點(diǎn)符號都是英文的。

輸入樣例：
33

輸出樣例：
Weak signals, readable with considerable difficulty.
