题目传送门 /* 题意:给了两堆牌,每次从首部取出一张牌,按颜色分配到两个新堆,分配过程两新堆的总数差不大于1 记忆化搜索(DFS+DP):我们思考如果我们将连续的两个操作看成一个集体操作,那么这个操作必然是1红1黑 考虑三种情况:a[]连续两个颜色相同,输出11:b[]连续两个相同,输出22: a[x] != b[y], 输出12:否则Impossible 详细解释:http://blog.csdn.net/jsun_moon/article/details/10254417 */ #incl…

URAL 1501 思路: dp+记忆化搜索 状态:dp[i][j]表示选取第一堆前i个和第二堆前j的状态:0:0多1个              1:0和1相等                2:1多一个         -2:不能达到题目所描述的状态 初始状态:dp[0][0]=1 状态转移:见代码 代码: #include<bits/stdc++.h> using namespace std; #define ll long long #define pb push_bck #defin…
