# Farmers League Solution codechef

A football league of N teams is taking place, where each team plays other teams once in single round robin fashion. A team gets 3 points for winning a game and 0 for losing (assume that no games end in a draw/tie). What is the maximum possible difference of points between the winning team and the second-placed team?

### Input Format

• The first line of input will contain a single integer T, denoting the number of test cases. Then the test cases follow.
• Each test case consists of a single line of input, containing a single integer N.

### Output Format

For each test case, output in a single line the maximum difference of points between first and second place.

• 1T105
• 2N109

### Sample Input 1

4
2
3
4
9


### Sample Output 1

3
3
6
12


### Explanation

Test case 1: There will only be one match played between the two teams, therefore one team wins by 3 points.

Test case 2: Let the three teams be A, B, C. If team A wins both the games against team B and team C, then team A will win by 3 points since one of team B and team C will win the game between them.

Test case 3: Let the four teams be A, B, C, D. One possibility is for A to win all its games, and then B beats C, C beats D, D beats B. This way, the winner has 9 points and second place has 3 points, making a difference of 6.

Test case 4: It can be shown that it’s not possible to achieve a difference higher than 12 when 9 teams play. One way of achieving this is for the winner to score 24 points and second place to score 12.
