ACM_0119 - FAST SOLVER
In this problem you are given six simple equations. You are also informed that correct values of x1, x2, x3, x5, x6, x7, are in the answer set A = {a1, a2, a3,…,an} for some integer n, where each ai is in the set of prime numbers between 2 to 20,000,000. The six equations are as follows.
c1 = x1x2
x4 = c4x1
c3 = x6x7
x8 = x7c2
c5 = x2x3
c6 = x6x5
Observe that c1, c2, c3, c4, c5, and c6 are positive integer constants at most (20,000,000)2. Given c1, c2, c3, c4, c5, and c6, your job is to find an efficient algorithm to solve these equations and report the correct values of x1, x2, x3, x5, x6, x7. You can be sure that these equations can be solved.
Input
The input file contains 6 integers separated by a blank representing c1, c2, c3, c4, c5, and c6, respectively.
Output
The output file has a single line reporting the correct values of x1, x2, x3, x5, x6, x7, respectively. Each value is separated by a blank. (In case there are many possible solutions, choose only one of them as the output.)
