Power and Mod

By Bhadra · Limits 1.5s, 512 MB

Exponentiation is a mathematical operation, written as b n , involving two numbers, the base b and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases:

$ b^n = b \times ... \times b \space (n \space times) $

In computing, the modulo operation finds the remainder after division of one number by another (sometimes called modulus). Given two positive numbers, a (the dividend) and n (the divisor), a modulo n (abbreviated as a mod n) is the remainder of the Euclidean division of a by n. For instance, the expression “5 mod 2” would evaluate to 1 because 5 divided by 2 leaves a quotient of 2 and a remainder of 1, while “9 mod 3” would evaluate to 0 because the division of 9 by 3 has a quotient of 3 and leaves a remainder of 0; there is nothing to subtract from 9 after multiplying 3 times 3.

Now, you are given the value of a, b and m. print the value of

$ a^b \space mod \space m $


The first line contains the number of test cases T (1 ≤ T ≤ 104).

The next T line contains three integers a, b (1 ≤ a, b ≤ 109) and m (1 ≤ m ≤ 264).


For each test case print the answer of the problem.


2 3 4
3 4 5
