Difficulty: EASY

One day Patrik met a magician.He asked magician for his magic pencil.So magician decided to give him magic pencil only if he correctely answers 
to his question. 
Magician gave him 3 numbers a, b and c and asked him to find the multiple of c which is closest to a^b.Help patrik to solve this problem and 
win magic pencil.

Note:If more than one answer is possible , print the smallest one.

Input Format: 

The first line contains T, the number of testcases. 
T lines follow, each line contains 3 space separated integers a, b and c respectively.

Output Format: 

For each test case , print the multiple of c which is closest to a^b

Constraints: 

1 ≤ T ≤ 10^5 

1 ≤ a ≤ 10^9 

-10^9 ≤ b ≤ 10^9

1 ≤ c ≤ 10^9 

0 < a^b ≤ 10^9
