reminder please note that in problem C, a[i],x,y,v may be negative! 2023-01-20 14:41:18

English Statements Update For problem C, "replace each $a_i$ with $\max(a_i, y)$ for $i \in [l'_i, r'_i]$" should be "replace each $a_k$ with $\max(a_k, y)$ for $k \in [l'_i, r'_i]$". 2023-01-20 14:00:55
English Statements Update For problem A, the first line of the input contains three integers $n, r, R$. For problem C, the condition \"$x_i \leq \max{l_i \leq k \leq r_i} a_i$\" should be \"$x_i \leq \max_{l_i \leq k \leq r_i} a_k$\". For problem D, subtask 5 is worth $30$ points. For problem E, the constraint should be $n \leq 300$ instead of $n \leq 400$. (Note: you may check the Chinese statements or the problem attachments for sample tests.) 2023-01-20 13:57:00

E题路径不交是点不交还是边不交

T1 输入格式中写ai是正整数，但数据范围中写ai可能等于0，所以ai保证是正整数吗

T1是否满足存在一个数，去掉它后答案为YES
