Knuckles, from Ugandan, is finding his queen. He accidentally find a ancient stele which curved two numbers on it. He reckon it as a clue to find his queen. Knuckles is very smart. He soon realizes that the rule between numbers.
The stele contains two numbers l,r which means the range from l ~ r .
Knuckles wants to find two different numbers x,y in the range,
in other word l <= x < y <= r.
And Knuckles also wants that x divides y( y%x == 0 ).
Knuckles thinks that the minimum sum of x+y will be the clue to find the queen. Because the stele is from Ugandan gods there is always an answer.
Help Knuckles find his queen or he will spit on you.
input contains two integer l and r ( 1 <= l < r <= 109 )
output contains two integer x and y ( l <= x < y <= r ) which x divides y.( remember print \n at the end of output and x ,y are seperated by a blank.)
