[CC-BSTRLCP]Count Binary Strings 题目大意: 对于一个长度为\(n\)的\(\texttt0/\texttt1\)串\(S\),如果存在一个切分\(i\),使得\(S_{[1,i]}\)与\(S_{[i+1,n]}\)的LCP长度\(>k\),那么称\(i\)是\(S\)的精准切分. 如果\(S\)至少有\(m\)个精准切分,那么称\(S\)是一个切分串. 给定\(n,k,m\),求有多少长度为\(n\)的切分串. \(1\le T\le 5\) \(1\le n…

A. You Are Given Two Binary Strings… You are given two binary strings x and y, which are binary representations of some two integers (let’s denote these integers as f(x) and f(y)). You can choose any integer k≥0, calculate the expression sk=f(x)+f(y)…

http://codeforces.com/gym/101161/attachments 这题通过打表,可以知道长度是i的时候的合法方案数. 然后得到f[1] = 2, f[2] = 3, f[3] = 5, f[4] = 8......这样的广义fib数列 现在要求f[k] + f[2k] + f[3k] + ...... + f[xk]的总和. 直接做很难做,我不知道f[i * k] = x * f[(i - 1) * k] + y * f[(i - 2) * k] 推不出系数的话,有一个结…

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 二进制数想加,并且保存在string中,要注意的是如何将string和int之间互相转换,并且每位相加时,会有进位的可能,会影响之后相加的结果.而且两个输入string的长度也可能会不同.这时我们需要新建一个string,它的长度是两…

Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 求数字字符串的二进制和. 同之前的数组代表数字,两个数组相加一样.仅仅只是进位变成了2.可能两个串的长度不一样,故逆转.从左到右加下去.最后再逆转. public static String addBinary(String a…

题目: Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 提示: 此题我的第一反应是把输入的两个字符串转化为数字,相加以后再把结果转化为二进制输出,但是测试用例中会有很大的输入,此时即使是long long型也会造成溢出,所以只能用最传统的由低位到高位逐位相加的方法去做. 代码: c…
