PAGAIN2 - Previous Prime (64 bit edition)
In this problem, you have to find the nearest prime number smaller than N.
Input
The first line contains an integer T specifying the number of test cases.
T lines follow, each line contains an integer N.
Output
For each test case, output the result on one line.
Example
Input: 3 5 10 17 Output: 3 7 13
Constraints
3 <= N <= 2^64 0 < T < 10^5
Information
Since Prime or Not, have the new cluster Cube instead of Pyramid, it appears there's a room for this classic problem now. Input is not randomly chosen. Prime Again and Prime After N are recommended problems before this one. Time limit is twice the time given by my deterministic_Python_code, but the input file is way too small, so there's still some weakness, and much faster code can get AC... Have fun ;-) Under construction - please be patient
