Easy#engineering #electronics #math· solved by 0 · time limit 2.0 s

Ohm's law: $V = I \times R$ . You are given two of voltage V (volts), current I (amps) and resistance R (ohms). Print the missing one: V and R with 2 decimals, I with 4 decimals.

Input

One line: X a Y b — two letters from V, I, R, each followed by its value.

Output

The missing letter and its value.

Constraints

All values are positive and at most $10^6$ ; R and I are never 0.

Sample 1
