Problem Statement

翻译中…

You are given sequences of positive integers $A$ and $B$ of length $N$. Process $Q$ queries given in the following forms in the order they are given. Each query is of one of the following three types.

翻译中…
  • Type $1$: Given in the form 1 i x. Replace $A_i$ with $x$.
  • Type $2$: Given in the form 2 i x. Replace $B_i$ with $x$.
  • Type $3$: Given in the form 3 l r. Solve the following problem and print the answer.
  • Initially, set $v = 0$. For $i = l, l+1, ..., r$ in this order, replace $v$ with either $v + A_i$ or $v \times B_i$. Find the maximum possible value of $v$ at the end.

It is guaranteed that the answers to the given type $3$ queries are at most $10^{18}$.

  • $1 \leq N \leq 10^5$
  • $1 \leq A_i \leq 10^9$
  • $1 \leq B_i \leq 10^9$
  • $1 \leq Q \leq 10^5$
  • For type $1$ and $2$ queries, $1 \leq i \leq N$.
  • For type $1$ and $2$ queries, $1 \leq x \leq 10^9$.
  • For type $3$ queries, $1 \leq l \leq r \leq N$.
  • For type $3$ queries, the value to be printed is at most $10^{18}$.
