Dice Game
This problem will be judged on CodeForcesGym. Original ID: 100502D
64-bit integer IO format: %I64d Java class name: (Any)
Gunnar and Emma play a lot of board games at home, so they own many dice that are not normal 6sided dice. For example they own a die that has 10 sides
with numbers 47,48,...,56 on it.
TherehasbeenabigstorminStockholm,soGunnar and Emma have been stuck at home without electricity for a couple of hours. They have finished playing all the games they have, so they came up with a new one. Eachplayerhas2dicewhichheorsherolls. Theplayer with a bigger sum wins. If both sums are the same, the game ends in a tie.
Task
Given the description of Gunnar’s and Emma’s dice, which player has higher chances of winning?
All of their dice have the following property: each die contains numbers a,a +1,...,b, where a and b are the lowest and highest numbers respectively on the die. Each number appears exactly on one side, so the die has b − a +1 sides.
Input
The first line contains four integers a1,b1,a2,b2 that describe Gunnar’s dice. Die number i contains numbers ai,ai +1,...,bi on its sides. You may assume that 1 ≤ ai ≤ bi ≤ 100. You can further assume that each die has at least four sides, so ai +3 ≤ bi.
The second line contains the description of Emma’s dice in the same format.
Output
Output the name of the player that has higher probability of winning. Output “Tie” if both players have same probability of winning.
