Anushree had to take the trial of chess for selection of InterNIT chess team. But many people were interested to take part in the trials, so she decided to knock out the contestants on their skills of chess. She decided of a problem statement such that you are given a board of n x n dimension,and the position of the horse (x,y) co-ordinate where x is the row no and y is the column no,find the percentage of positions on the n x n board you can cover starting from the given point.Can you solve this problem?
Input:
First line contains the number of testcases t.
Next t lines contain 3 numbers,
first is size n of the board,
second is the value of x,
and third is the value of y.
Output:
Output should contain the single number telling the percentage of area upto 2 decimals for each testcase on a new line.
constraints:
1<=t<=100
3<=n<=30
1<=x,y<=n
