计算两个数的平方和（3分）
题目内容:
从键盘读入两个实数，编程计算并输出它们的平方和，要求使用数学函数pow（x,y）计算平方值，输出结果
保留2位小数。
提示:
使用数学函数需要在程序中加入编译预处理命令#include
以下为程序的运行结果示例:
pleaseinputxandy:
1.2,3.4?
result=13.00
输入格式:
"%f,%f"
输出格式:
输入提示信息:
"Pleaseinputxandy:
\n"输出格式:
"Result=%.2f\n"
为避免出现格式错误，请直接拷贝粘贴题目中给的格式字符串和提示信息到你的程序中。

逆序数的拆分计算（3分）
题目内容:
从键盘输入一个4位数的整数，编程计算并输出它的逆序数（忽略整数前的正负号）。
例如，输入-1234，
忽略负号，由1234分离出其千位1、百位2、十位3、个位4，然后计算4*1000+3*100+2*10+1=4321，
并输出4321。
再将得到的逆序数4321拆分为两个2位数的正整数43和21，计算并输出拆分后的两个数
的平方和的结果。
以下是程序的运行结果示例:
Inputx:
-1234?
y=4321
a=43,b=21
result=2290
输入格式:
"%d"
输出格式:
输入提示信息:
"Inputx:
\n"
逆序数输出格式:
"y=%d\n"
逆序数拆分后的输出格式:
"a=%d,b=%d\n"
平方和的输出格式:
"result=%d\n"
