( 6264 ) A Treasure Hunt PROGRAMMING implementation math number theory 1200

B'Captain Bill the Hummingbird and his crew recieved an interesting challenge offer. Some stranger gave them a map, potion of teleportation and said that only this potion might help them to reach the treasure. Bottle with potion has two values x and y written on it. These values define four moves which can be performed using the potion: Map shows that the position of Captain Bill the Hummingbird is (x1, xe2 x80 x89y1) and the position of the treasure is (x2, xe2 x80 x89y2). You task is to tell Captain Bill the Hummingbird whether he should accept this challenge or decline. If it is possible for Captain to reach the treasure using the potion then output "YES", otherwise "NO" (without quotes). The potion can be used infinite amount of times. The first line contains four integer numbers x1, xe2 x80 x89y1, xe2 x80 x89x2, xe2 x80 x89y2 ( xe2 x80 x89- xe2 x80 x89105 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x1, xe2 x80 x89y1, xe2 x80 x89x2, xe2 x80 x89y2 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105) -- positions of Captain Bill the Hummingbird and treasure respectively. The second line contains two integer numbers x, xe2 x80 x89y (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x, xe2 x80 x89y xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105) -- values on the potion bottle. Print "YES" if it is possible for Captain to reach the treasure using the potion, otherwise print "NO" (without quotes). In the first example there exists such sequence of moves: '...
