| 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 $k \in [l'_i, r'_i]$". |

| 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.) |
