There will be 2 cases to consider: 1. R[X] <= C: we can simply swap the position of ball X and Y, without impacting the final answer. 2. R[X] > C: we can not put ball X to box C, this will turn the answer from yes to no. Solution: 1. sort all [L, R] in ...
i passed hours looking looking for the testcase where my code fail in the A problem , can you please share the link for atcoder testcases ? mayberng_58can help :)
\end{cases}$$ 很好理解,如果理解不了建议补一补布尔运算。 ### 定初始状态 我们的初始状态只有 $f_{0,0}$ 和 $f_{0,1}$。显然,他们都等于 $1$。 最后答案为 $f_{n,1}$。 ```cpp //Don't act like a loser. //This code is written by huayucaiji ...

\[\begin{cases}f_{x,y}=f_{y,x}=\frac{f_{x,y}+f_{y,x}}2\\f_{x,j}=f_{y,j}=\frac{f_{x,j}+f_{y,j}}2&j\not=x,y\\f_{j,x}=f_{j,y}=\frac{f_{j,x}+f_{j,y}}2&j\not=x,y\end{cases} \] 于是就得到了一个优秀的\(O(Qn)\)的\(DP\),这道题也就做...
