5.　　定义一个函数long invers(long x)，x为一个6位整数，函数功能是取x的高3位数（赋给h）和低3位各位数字（可从高位到低位依次存入变量a、b和c），将a、b和c逆序组合为一个整数t，计算h+t并将结果返回。-5. Define a function long invers (long x), x is a 6-bit integer, the function function is to take the high x 3 digits (assigned to h) and low number of 3 Members (in order from highest to lowest into variable a, b and c), the a, b and c reverse combination of an integer t, h+ t calculated and the results returned.
