Average of three

Read three whole numbers and print their average with exactly two decimal places.

What to build

A program that reads three numbers and shows their average neatly.

Requirements

  • Read three whole numbers.
  • Print their average with exactly two decimal places.

Input

Three lines, each with one whole number from 0 to 100.

Output

The average, with two decimal places, for example 76.33.

Constraints

Each number is from 0 to 100.

Example

Input:

72
85
72

Output:

76.33

Why it works

Adding first and then dividing by 3 gives the average, and :.2f rounds what is shown without changing the value.

Examples

Example 1 · Input
72
85
72
Expected output
76.33
Example 2 · Input
100
100
100
Expected output
100.00

Prompts inside input() are ignored when checking, so input("n: ") is fine.

Hints

Hint 1

f"{value:.2f}" shows two decimal places.

Solution

Show one correct solution (try it yourself first)
a = int(input())
b = int(input())
c = int(input())
print(f"{(a + b + c) / 3:.2f}")
