时间换算（5分）

题目内容：

UTC是世界协调时，BJT是北京时间，UTC时间相当于BJT减去8。现在，你的程序要读入一个整数，表示BJT的时和分。整数的个位和十位表示分，百位和千位表示小时。如果小时小于10，则没有千位部分；如果小时是0，则没有百位部分；如果分小于10分，需要保留十位上的0。如1124表示11点24分，而905表示9点5分，36表示0点36分，7表示0点7分。

有效的输入范围是0到2359，即你的程序不可能从测试服务器读到0到2359以外的输入数据。

你的程序要输出这个时间对应的UTC时间，输出的格式和输入的相同，即输出一个整数，表示UTC的时和分。整数的个位和十位表示分，百位和千位表示小时。如果小时小于10，则没有千位部分；如果小时是0，则没有百位部分；如果分小于10分，需要保留十位上的0。

提醒：要小心跨日的换算。

输入格式:

一个整数，表示BJT的时和分。整数的个位和十位表示分，百位和千位表示小时。如果小时小于10，则没有千位部分；如果小时是0，则没有百位部分；如果小时不是0而且分小于10分，需要保留十位上的0。

输出格式：

一个整数，表示UTC的时和分。整数的个位和十位表示分，百位和千位表示小时。如果小时小于10，则没有千位部分；如果小时是0，则没有百位部分；如果小时不是0而且分小于10分，需要保留十位上的0。

输入样例：

933

输出样例：

133

时间限制：500ms内存限制：32000kb

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int BJT = in.nextInt();
		int UTC;
		if ( BJT < 800)
		{
			UTC = BJT + 1600;
		}
		else
		{
			UTC = BJT - 800;
		}
		System.out.println(UTC);
		}
}

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：

输出样例：

Weak signals, readable with considerable difficulty.
