In the realizing of shortest path algorithm and bus take algorithm, using the pointer in Delphi language to make up the queen, stack replacing the using of array in other system, dynamically assign memory, save memory space and operation time.

• 而在最短路径搜索和转乘公车方案的算法实现上，发挥了Delphi语言的所长，利用指针链接的技术，代替用数组来组成队列、栈，达到动态分配内存，节省内存空间及运算时间。
