    Special Binary String

    Special Binary String Problem: Special binary strings are binary strings with the following two properties 接着交换任意两个连续位置的special binary string,取lexicographically最大的。 各位且慢,举个例子”1010”,是special binary string,首尾的确分别是1和0,但很遗憾”01”并不是special binary string啊,那怎么用递归解决啊! 它除了首尾的子串一定是special binary string。 嘿,既然能够找到第一个count = 0的special binary string,并且确保了子问题也是special binary string,就可以递归求解了。

    Leetcode: Add Binary

    题目: Given two binary strings, return their sum (also a binary string). //十进制转二进制 string result;//结果字符串 //临时存储计算的二进制结果,计算出来的余数要reverse下 vector<int> binary quotient /= 2; } binary.push_back(remainder); vector<int>::size_type size = binary.size(); //逆序遍历binary将每个int转为char装入result中 for (size_t i = size; i ! = 0; i--) { result.push_back(binary[i - 1] + '0'); } return result

    【leetcode】Add Binary

    Question: Given two binary strings, return their sum (also a binary string). blen--; } return sum; } }; Anwser 2:      wrong for large and large binary write int main() function return num2str( str2num(a) + str2num(b) ); } }; 注意点: 1) 思路是将binary 先转化成整数(int, long, ulong, long long等),然后相加(a + b),最后再将整数和转化回binary字符串 2) 对小数据,此方法可行(Judge Small is ok)
