2

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]内有效的数字,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.

		int strength;// S(Strength) 信号强度即大小
		Scanner in = new Scanner(System.in);
		x = in.nextInt();
		readability = x / 10;
		strength = x % 10;

		switch (strength) {
		case 1:

		switch (readability) {

			System.out.print("readable with practically no difficulty.");
			break;
		case 5:
			System.out.print("perfectly readable.");
