C8051F120和C8051F130的基础例程源码，学习该系列单片机的号资料(C8051F120 and C8051F130 source based routine, learning the number of the MCU data)

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)
