Difficulty—

You are given a person's systolic blood pressure, $A$, and diastolic blood pressure, $B$. Find the mean arterial pressure, $C$, which we define as follows: * $C = \frac{A-B}{3} +B$. ## Constraints * $50 \leq B \leq A \leq 300$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $A$ $B$ [samples]

Samples

Input #1

130 100

Output #1

110

We have $C = \frac{130-100}{3} +100 = 10 + 100 = 110$.

Input #2

300 50

Output #2

133.3333333

Note that although all the values in input are integers, the value to output may not be an integer.

Input #3

123 123

Output #3
