, so the is not a valid solution. In the second sample case: On the first level, ZS the coder pressed the ' + ' button 999999999999999998 times (and the number on screen is initially 2), so the number became 2 + 999999999999999998 1 = 1018. Then, ZS the coder pressed the "button, and the number became. After then, on the second level, ZS pressed the ' + ' button

Ma Xiao theorem of sum-up fee for number theory algorithm \ (A^{p-1} \equiv 1 \pmod{p}\space ((a,p) =1,isprime (p)) \) Proof: LinkThe general form is given here: Consider the remainder of any positive integer \ (A\mod p\space ((a,p) =1) \) , with \ (1,2,3,\ldots, p-1\).Then we take any positive integer \ (a ' ((a ', p) =1) \), the remaining system is multiplied by \ (a ' \) and then

. Programming implementation: Knowing the computational formula, we just need to do it with simple programming techniques. There are many ways to achieve the value of Euler functions, and here we give a direct implementation method. That is to walk out n all the prime factors and then apply the formula, the optimization technique is very similar with our in the "Number theory and its application-prime prob

, when k equals a certain value, the number of pig text in the face is N. K However, it is also quite a lot to keep n/k from n characters. Ipig predicts that if all the possible k's cases add up to p, then the cost of studying ancient writings will be the P-th side of G. Now he wants to know what the cost of studying ancient writings in the Pig Kingdom is. Since Ipig thinks this number can be astronomical,

A preprocessing method for getting prime numbers is wrong with prime factor decomposition, so I am crying, First, the maximum value of AI is 10 ^ 9, and N is 500.

individual digits added. I do the simulation at the first glance. When simulating, it is important to note that the number entered may be very large, so it is not possible to use int, which should be handled by string. The simulation procedure code is as follows:#include There is also a solution to the knowledge of number theory.

It states: Every even integer, greater than 2, can be expressed as the sum of of the primes [1]. Now your task was to check whether this conjecture holds for integers up to 107. Input Input starts with an integer T (≤300), denoting the
