思路很简单,就是存储之前运算的结果,然后递归class Solution {public: int**
dp; int get_min_sum(vector > &grid, int m, int n) { if (dp[m][n] != -1)
...

给两个长度分别为n和m的序列,现在有两种操作:1.分别选择两个序列的一个非空前缀,切两个前缀的最后一位相同,删除之,得到1分(只累计),消耗e;2.直接删除两个序列,消耗值定于两个序列之前删除的元素个数之和,并且使得得到的分有效(之前没有有效分)
(1?≤?n,?m?≤?105; 1?≤?s?≤?3·105; 103?≤?e?≤?104),s代表总能量,e表示一次操作的消耗...

今天在写栈碰到 了一个问题关于c语言参数传递的让我郁闷了半天
我只发现了两个问题一个
实参sum(a,b)
形参sum(int a,int b)或者sum(int &a,int &b)
实参sum(&a,&b)
形参sum(int *a,int *b)
这个就是c函数传地址与传引用传值!...

Given two binary strings, return their sum (also a binary string).
For example,
a = "11"
b = "1"
Return "100".
思路同十进制的大数相加。代码如下:
class Solution {
public:
string addBinary(string a, str...
