For this problem, you will be given two side lengths of a triangle and will be required to determine the length of the other side. You can assume that all input will be provided for a valid right triangle. The two side lengths you will be given correspond to the common variables $A$ and $C$, meaning one side and the hypotenuse. You should then output the length of side $B$. Two space-separated integer values that represent $A$ and $C$ respectively. A single floating point value that represents the length of side $B$. Make sure that you are finding the length of side $B$ and not $C$(the hypotenuse). ## Input Two space-separated integer values that represent $A$ and $C$ respectively. ## Output A single floating point value that represents the length of side $B$. [samples] ## Note Make sure that you are finding the length of side $B$ and not $C$(the hypotenuse).

**Definitions** Let $ A, C \in \mathbb{R}^+ $ be the given side and hypotenuse of a right triangle, respectively. Let $ B \in \mathbb{R}^+ $ be the unknown side to be determined. **Constraints** 1. $ A > 0 $, $ C > 0 $ 2. $ A < C $ (since $ C $ is the hypotenuse) 3. The triangle is a valid right triangle with legs $ A $ and $ B $, and hypotenuse $ C $. **Objective** Compute $ B $ using the Pythagorean theorem: $$ B = \sqrt{C^2 - A^2} $$
