21022번 - Three Points for a Win 다국어

문제

Three points for a win is a common point system used in competitions such as football (soccer) leagues or group tournaments. In this system, a team is awarded 3 points if they win a match, 1 point for a draw, and 0 points if they lose. Finally, the team with the most points wins the league.

Supposed BINUS’ football team joins a league and has played N matches. At the i^th match, BINUS’ team scores A_i vs B_i against their opponent. If A_i > B_i, then BINUS’ team wins the i^th match; if A_i < B_i, then BINUS’ team loses the match; otherwise, if A_i = B_i, then it’s a draw. Given the score of each match, your task is to determine the total points accumulated by BINUS’ team.

For example, let N = 4 where A_1..4 = {3, 0, 2, 4} and B_1..4 = {1, 1, 2, 3}.

• At the first match, BINUS’ team wins by 3 vs 1.
• At the second match, BINUS’ team loses by 0 vs 1.
• The third match is a draw (both have the same score of 2).
• At the fourth match, BINUS’ team wins by 4 vs 3.

Therefore, the total points accumulated by BINUS’ team in this example is: 3 +たす 0 +たす 1 +たす 3 =わ 7.
