即使你之前了解过逻辑回归，我认为这里还是有些新的、有趣的东西等着你去发现和了解，所以现在开始进入正题 逻辑回归是一个用于二分类($binary\ classification$)的算法。

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。
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

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）

问题：二叉树中序遍历 递归实现 /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode
题目： Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the C++参考示例代码： /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode *left
这题有意思的是，并不能直接将求最大深度的max改为min就完了，有很多坑在里面。一开始我以为只要将[],[0],[1,2]等情况考虑掉就可以了，其实在只有一边又...

二叉树的前序遍历 递归实现 /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode
题意：二叉树的最小深度 注意 1.当root为空的时候直接返回0，因为MIN赋值很大，所以如果不单独预判的话会返回MIN 2.判断树的深度应...

https://blog.csdn.net/zhangjunhit/article/details/89914423 Training Binary Weight Networks via Semi-Binary Decomposition ECCV2018 CNN模型的压缩或加速总体上分为三类： pruning-based methods, low-rank decomposition 3.3 Featuremap-Oriented Semi-Binary Factors 直接对网络所有层的 W 使用 semi-binary decomposition 进行分解有两个弊端：1）在前向计算时 2）直接对整个网络使用 semi-binary decomposition 会造成精度的较大下降，因为量化误差通过多层的累积。 如何解决这个问题了？ learn the semi-binary components via minimizing the output featuremap’s quantization loss ?
Example 1: Input: 22 Output: 2 Explanation: 22 in binary is 0b10110. In the binary representation of 22, there are three ones, and two consecutive pairs of 1's. Example 2: Input: 5 Output: 2 Explanation: 5 in binary is 0b101. Example 3: Input: 6 Output: 1 Explanation: 6 in binary is 0b110. Example 4: Input: 8 Output: 0 Explanation: 8 in binary is 0b1000.
