In a Chess match “a + b”, each player has a clock which shows aa minutes at the start and whenever a player makes a move, bb seconds are added to this player’s clock. Time on a player’s clock decreases during that player’s turns and remains unchanged during the other player’s turns. If the time on some player’s clock hits zero (but not only in this case), this player loses the game.

There’s a 3 + 2 blitz chess match. After NN turns (i.e. ⌊N+12⌋⌊N+12⌋ moves made by white and ⌊N2⌋⌊N2⌋ moves made by black), the game ends and the clocks of the two players stop; they show that the players (white and black) have AA and BB seconds left respectively. Note that after the NN-th turn, b=2b=2 seconds are still added to the clock of the player that made the last move and then the game ends.

Find the total duration of the game.

Input

The first line of the input contains a single integer TT denoting the number of test cases. The description of TT test cases follows.
The first and only line of each test case contains three space-separated integers NN, AA and BB.

Output

For each test case, print a single line containing one integer — the duration of the game.

there is at least one valid game consistent with the input

0

Explanation

Example case 1: The total time given to both clocks after 1010 turns is 2⋅(180+10)=3802⋅(180+10)=380 seconds. The total time left at the end is 0+2=20+2=2 seconds. The duration of the game is 380−2=378380−2=378 seconds.

Blitz Problem Codechef solution in C++ 14


int main()
{
    int t;
    cin>>t;
    while(t--)
    {
        int n,a,b;
        cin>>n>>a>>b;
        cout << 360+2*n-(a+b) << "\n";

    }
    return 0;
}

Blitz Problem Codechef solution in Python 3

T = int(input(""))
for i in range (0,T):
    n,a,b = map(int,input().split())
    t = 2*(180+n)
    tl = a+b
    d = t-tl
    print(d)
