Slavic's Exam
Description
Slavic has a very tough exam and needs your help in order to pass it. Here is the question he is struggling with:
There exists a string $s$, which consists of lowercase English letters and possibly zero or more "?".
Slavic is asked to change each "?" to a lowercase English letter such that string $t$ becomes a subsequence (not necessarily continuous) of the string $s$.
Output any such string, or say that it is impossible in case no string that respects the conditions exists.
The first line contains a single integer $T$ ($1 \leq T \leq 10^4$) — the number of test cases.
The first line of each test case contains a single string $s$ ($1 \leq |s| \leq 2 \cdot 10^5$, and $s$ consists only of lowercase English letters and "?"-s) – the original string you have.
The second line of each test case contains a single string $t$ ($1 \leq |t| \leq |s|$, and $t$ consists only of lowercase English letters) – the string that should be a subsequence of string $s$.
The sum of $|s|$ over all test cases doesn't exceed $2 \cdot 10^5$, where $|x|$ denotes the length of the string $x$.
For each test case, if no such string exists as described in the statement, output "NO" (without quotes).
Otherwise, output "YES" (without quotes). Then, output one line — the string that respects all conditions.
You can output "YES" and "NO" in any case (for example, strings "yEs", "yes", and "Yes" will be recognized as a positive response).
If multiple answers are possible, you can output any of them.
