[Note: Here a + b > 0]

 

Example

if a - b = 2 and ab = 24 then

a + b = 10

 

The Input

Input file contain a series of line, each line contains two integer numbers X and Y (0<X,Y<1000000).

 

The Output

For each line of input, output will show one integer numbesr which the value of a + b in a separate line.
