In the C programming language, strings are not a native data type. In fact, they are just an array of characters, with a sentinel NULL value used to denote the end of the string. Since working with strings is a very important thing to do in programming languages, the C standard library has several very useful functions for string manipulation: among them are strcpy, strcmp, strtol, strtok, strlen, and strcat.
However, there is one function that not many know about, and even fewer use it: the strfry function. strfry takes an input string and randomly swaps a random number of characters.
Given two strings, determine if it is possible that the second string is the first string, strfried.
The input begins with a number 0 < N < 1001, the number of test cases.
Each test case consists of a single line containing two strings of lowercase English characters, separated by a single space; these are the two strings in question. Each string is at most 1000 characters long.
Output one line for each test case, containing either "Impossible" or "Possible" (without quotes).
