Family View

Steam is a digital distribution platform developed by Valve Corporation offering digital rights management (DRM), multiplayer gaming and social networking services. A family view can help you to prevent your children access to some content which are not suitable for them.

Take an MMORPG game as an example, given a sentence T, and a list of forbidden words {P}, your job is to use '*' to subsititute all the characters, which is a part of the substring matched with at least one forbidden word in the list (case-insensitive).

For example, T is: "I love Beijing's Tiananmen, the sun rises over Tiananmen. Our great leader Chairman Mao, he leades us marching on."

And {P} is: {"tiananmen", "eat"}

The result should be: "I love Beijing's *********, the sun rises over *********. Our gr*** leader Chairman Mao, he leades us marching on."

The first line contains the number of test cases. For each test case:
The first line contains an integer $n$, represneting the size of the forbidden words list $P$. Each line of the next $n$ lines contains a forbidden words $P_i~(1\le |P_i|\le 1000000, \sum |P_i| \le 1000000)$ where $P_i$ only contains lowercase letters.

The last line contains a string $T~(|T| \le 1000000)$.

For each case output the sentence in a line.
