When numerous queries each admit a binary search solution, but performing binary search individually for every query is too slow, we can process all queries together using a technique known as simultaneous binary search (also called "parallel binary search" or "global binary search"). This approach requires: Queries to be h ...

In this problem, we are given an array $a$ of length $n$ and a target array $b$ of length $m$. Each element $a_i$ has an associated deletion cost $p_i$. We need to find the minimum cost to transform $a$ in to $b$ using a specific "strange function" $f(a)$, or determine if it is impossible. Condition Analysis The function $f(a)$ genera ...
