信号报告(5分)
题目内容:
无线电台的RS制信号报告是由三两个部分组成的:
R(Readability) 信号可辨度即清晰度.
S(Strength) 信号强度即大小.
其中R位于报告第一位,共分5级,用1—5数字表示.
-
1---Unreadable
-
2---Barely readable, occasional words distinguishable
-
3---Readable with considerable difficulty
-
4---Readable with practically no difficulty
-
5---Perfectly readable
报告第二位是S,共分九个级别,用1—9中的一位数字表示
-
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
现在,你的程序要读入一个信号报告的数字,然后输出对应的含义。如读到59,则输出:
- Extremely strong signals, perfectly readable.
输入格式:
一个整数,信号报告。整数的十位部分表示可辨度,个位部分表示强度。输入的整数范围是[11,59],这个范围外的数字不可能出现在测试数据中。
输出格式:
一句话,表示这个信号报告的意义。按照题目中的文字,先输出表示强度的文字,跟上逗号和空格,然后是表示可辨度的文字,跟上句号。注意可辨度的句子的第一个字母是小写的。注意这里的标点符号都是英文的。
输入样例:
33
输出样例:
- Weak signals, readable with considerable difficulty.
