基于单片机MSP430的 步进电机控制 测距程序 (MSP430 microcontroller-based stepper motor control ranging program)

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.)
