題干：

There is a point?PP?at coordinate?(x,y)(x,y).?
A line goes through the point, and intersects with the postive part of?X,YX,Yaxes at point?A,BA,B.?
Please calculate the minimum possible value of?|PA|?|PB||PA|?|PB|.

Input

the first line contains a positive integer T,means the numbers of the test cases.?

the next T lines there are two positive integers X,Y,means the coordinates of P.?

T=500T=500,0<X,Y≤100000<X,Y≤10000.?

Output

T lines,each line contains a number,means the answer to each test case.?


?

Sample Input

1 2 1

Sample Output

4in the sample $P(2,1)$,we make the line $y=-x+3$,which intersects the positive axis of $X,Y$ at (3,0),(0,3).$|PA|=\sqrt{2},|PB|=2\sqrt{2},|PA|*|PB|=4$,the answer is checked to be the best answer.
