Description A sequence consisting of one digit, the number 1 is initially written into a computer. At each successive time step, the computer simultaneously tranforms each digit 0 into the sequence 1 0 and each digit 1 into the sequence 0 1. So, afte…

题意: 有一个01串,每一步都会将所有的0变为10,将所有的1变为01,串最开始为1. 求第n步之后,00的个数 分析: 刚开始想的时候还是比较乱的,我还纠结了一下000中算是有1个00还是2个00 最终想明白后,并不会出现这样的子串. 总结了几个要点: 第n步之后,串的长度为2n,且0和1的个数相等,分别为2n-1 1经过两步变化为1001,所以每个1经过两步变化就会得到一个00,而且这个00分别被左右两边一个1包围着,不会与其他数字凑出额外的00 0经过两步变化为0110,所以00就会变成0…

这道题目的意思是:一开始有一个数字 1 ,在接下来的时间中,计算机会按照如下规则进行扩展:                0 –> 1 0                1 –> 0 1 求n秒之后,有多少对相邻的0. 例如1 0 0 1有 1 对相邻的0.   这道题目是一道规律题,可以直接例举前面的数据得到规律: 0 0 1 1 3 5 11 21 43 85 通过例举的数据可以很明显的看出,从第 1s 开始,如果是偶数秒,那么b[ i ] = b[ i – 1 ] * 2 – 1,而奇数…

http://acm.hdu.edu.cn/showproblem.php?pid=1041 有一个初始只有一个1的串 每次都按①0 -> 10;②1 -> 01;这两条规则进行替换 形如:n = 1  1 n = 2  01 n = 3  1001 ... 求经过n步替换之后 串中只含复数个0的连续子串(不难发现,这种子串只能是‘00’)的出现次数 因为0<n<=1000的限制 在最坏情况下(n==1000)串的长度将达到2^1000位 排除了直接模拟上述替换过程的可能 列出前几…

https://vjudge.net/problem/UVA-1647 题意: 开始有一个1,接下来每一步1变成01,0变成10 问n不之后00的个数 打表找规律 第3步之后: 如果第i步之后有x个字符, 那么第i+1步之后 的后x个字符与第i步一样 前x个字符是第i步取反 所以00得个数由三部分组成 1.上一步00的个数 2.上一步11的个数 3.当i为偶数时,前x个字符的最后一个是0,后x个字符的第一个是0,00个数+1 f[i][0]=f[i-1][0]+f[i-1][1]+!(i&1)…

本题假设编程是使用DP思想直接打表就能够了. 假设是找规律就须要数学思维了. 规律就是看这些连续的0是从哪里来的. 我找到的规律是:1经过两次裂变之后就会产生一个00: 00经过两次裂变之后也会产生新的00:故此须要记录好1和00出现的次数就能够递推出后面的00出现的数据了. 公式就是tbl00[i] = tbl00[i-2] + tbl1[i-2]; 当中tbl00是记录00出现的次数,tbl1是出现1出现的次数. 公式事实上是能够化简的,只是我懒得化简了.这种公式非常清楚了. 只是因为这种数…

题意:初始串为一个1,每一步会将每个0改成10,每个1改成01,因此1会依次变成01,1001,01101001,……输入n(n<=1000),统计n步之后得到的串中,"00"这样的连续两个0出现了多少次. 分析:找规律,输出n等于20之前所有的结果 得到结论,i为奇数时,a[i] = a[i - 1] * 2 - 1; i为偶数时,a[i] = a[i - 1] * 2 + 1. import java.util.*; import java.math.BigInteger;…

题意:给一个初始值1,每步操作将1替换为01,将0替换为10.问N步操作后有多少对连续的0. 解法:f[i]表示第i步后的答案.可以直接打表发现规律--奇数步后,f[i]=f[i-1]*2-1;偶数步后,f[i]=f[i-1]*2+1;至于原因--我只能简单说一点.第i步后的答案可由i-1步后的"01"+"1"+"0"的个数推出,而"01"*2+"1"+"0"=01串的总个数.用x表示i…
