Problem 2: The Lead Game, (K Narayan Kumar, CMI)

The game of billiards involves two players knocking 3 balls around on a green baize table. Well, there is more to it, but for our purposes this is sufficient.

The game consists of several rounds and in each round both players obtain a score, based on how well they played. Once all the rounds have been played, the total score of each player is determined by adding up the scores in all the rounds and the player with the higher total score is declared the winner.

The Siruseri Sports Club organises an annual billiards game where the top two players of Siruseri play against each other. The Manager of Siruseri Sports Club decided to add his own twist to the game by changing the rules for determining the winner. In his version, at the end of each round the leader and her current lead are calculated. Once all the rounds are over the player who had the maximum lead at the end of any round in the game is declared the winner.

Consider the following score sheet for a game with 5 rounds:

    Round     Player 1       Player 2

      1         140             82
      2          89            134 
      3          90            110 
      4         112            106
      5          88             90 

The total scores of both players, the leader and the lead after each round for this game is given below:

    Round      Player 1       Player 2     Leader     Lead

      1          140           	 82       Player 1     58
      2          229           	216       Player 1     13
      3          319           	326       Player 2      7
      4          431           	432       Player 2      1
      5          519           	522       Player 2      3

The winner of this game is Player 1 as he had the maximum lead (58 at the end of round 1) during the game.

Your task is to help the Manager find the winner and the winning lead. You may assume that the scores will be such that there will always be a single winner. That is, there are no ties.

Input format

The first line of the input will contain a single integer N (N ≤ 10000) indicating the number of rounds in the game. Lines 2,3,...,N+1 describe the scores of the two players in the N rounds. Line i+1 contains two integer Si and Ti, the scores of the Player 1 and 2 respectively, in round i. You may assume that 1 ≤ Si ≤ 1000 and 1 ≤ Ti ≤ 1000.

Output format

Your output must consist of a single line containing two integers W and L, where W is 1 or 2 and indicates the winner and L is the maximum lead attained by the winner.

Test Data

The range of values over which your program is to be tested is mentioned above. In addition, 50% of the test cases will also satisfy N ≤ 1000.


We now illustrate the input and output formats using the example described above.

Sample input:

140 82
89 134
90 110
112 106
88 90
