PROGRAMMING:Finding the hypotenuse of a right triangle

It is required to read in two right sides a and B of a right triangle, and then output the length of its hypotenuse C. Note: right triangle: $$a ^ {2} + B ^ {2} = C ^ {2}$$
###Input format:
Enter an integer a and B no more than 100 in each of the two lines to represent the two right sides of the right triangle.
###Output format:
Output the corresponding slant length in one line, and keep 2 decimal places.
###Input example:
Here is a set of inputs. For example:
```in
three
four
```
###Output example:
The corresponding output is given here. For example:
