You are given:
- An integer non-decreasing array $A$ of $n$ integers.
- $q$ queries, each is an integer $x$, find the smallest $i$ that $A_i = x$.
### Input
- The first line contains 2 integer $n, q$.
- The second line contains $n$ space-separated integers $A_i$.
- The next $q$ lines, each contains an single integer $x$, a query.
### Output
- Print $q$ lines, $i^{th}$ line is the answer to query $i$. Print `-1` if $x$ cannot be found.
### Constraints
- $1 \le n, q \le 10^{5}$.
- $1 \le A_i \le 10^9$.
