Revenge of Fibonacci 题意:给定fibonacci数列的前100000项的前n位(n<=40);问你这是fibonacci数列第几项的前缀?如若不在前100000项范围内,输出-1: 思路:直接使用数组模拟加法,再用Trie树插入查找即可:但是一般使用new Trie()的代码都是MLE的.反而我之前写的,直接得到数组大小的maxnode版本的内存可以接受:并且还有一点就是前40位的精度问题:由于是自己计算出来的finboncci数列,并不是系统给的,所以1的进位不会形成很长…

题意:在前100000个Fibonacci(以下简称F)数字里,能否在这100000个F里找出以某些数字作为开头的F.要求找出下标最小的.没找到输出-1. 代码:(Accepted,0.250s) //UVa12333 - Revenge of Fibonacci //Accepted 0.250s //#define _XIENAOBAN_ #include<iostream> #include<cstring> #define MAXS 0xffffff #define CIN…
将斐波那契的前100000个,每个的前40位都插入到字典树里(其他位数删掉),然后直接查询字典树就行. 此题坑点在于 1.字典树的深度不能太大,事实上,超过40在hdu就会MLE…… 2.若大数加法时,保存的位数过少,就会导致低位误差,累积起来就可能导致前40位产生错误,解决办法是提高精度. #include<iostream> #include<cstring> #include<string> #include<cstdio> using namespa…
