# Nearest Value

Find the nearest value to the given one.

You are given a set of integers and a value for which you need to find the nearest one.

For example, we have the following sequence of numbers: 4, 7, 10, 11, 12, 17, and we need to find the nearest value to the number 9. If we sort this sequence in the ascending order, then to the left of number 9 will be number 7 and to the right - will be number 10. But 10 is closer than 7, which means that the correct answer is 10.

A few clarifications:

- If 2 numbers are at the same distance, you need to choose the smallest one;
- The sequence of numbers is always non-empty;
- The given value can be in this sequence, which means that it’s the answer;
- The sequence may contain both positive and negative numbers, but they are always integers;
- The sequence isn’t sorted and consists only unique numbers.

**
Input:
**
Two arguments. A set of integers. The sought value as an integer.

**
Output:
**
An integer.

Examples:

assert nearest_value({17, 4, 7, 10, 11, 12}, 9) == 10 assert nearest_value({17, 4, 7, 10, 11, 12}, 8) == 7 assert nearest_value({17, 4, 8, 10, 11, 12}, 9) == 8 assert nearest_value({17, 4, 9, 10, 11, 12}, 9) == 9

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)
