吝啬的国度时间限制：1000 ms  |  内存限制：65535 KB难度：3描述在一个吝啬的国度里有N个城市，这N个城市间只有N-1条路把这个N个城市连接起来。现在，Tom在第S号城市，他有张该国地图，他想知道如果自己要去参观第T号城市，必须经过的前一个城市是几号城市（假设你不走重复的路）。输入第一行输入一个整数M表示测试数据共有M(1每组测试数据

思路：直接暴力模拟肯定不行。我们考虑到第n个字符串由第n-1个字符串个第n-2个字符串相加得到，如果我们要找第m个字符，m<=fib[n-1]的话，我们就可以转成求第n-1个字符串的第m个字符，否则，就转换成求第n-2个字符串的第m-fib[a-1]个字符。这样的话就能建立递归表达式来求救此问题，当然，首先要求出前90个Fibonacii数的值。
