# Problem

In China，there is an ancient mathematical book, called "The Mathematical Classic of Sun Zi"(《孙子算经》). In the book, there is a classic math problem: “今有物不知其数，三三数之剩二，五五数之剩三，七七数之剩二，问物几何？” 

Ahh, Sorry. I forgot that you don't know Chinese. Let's translate it to English:

There is a unkown positive integer `n`. We know: 

`n % 3 = 2`, and `n % 5 = 3`, and `n % 7 = 2`. 

What's the minimum possible positive integer `n`?

The correct answer is `23`.

# Task

You are given three non-negative integers `x,y,z`. They represent the remainders of the unknown positive integer `n` divided by 3,5,7.

That is: `n % 3 = x, n % 5 = y, n % 7 = z`

Your task is to find the minimum possible positive integer `n` and return it.

# Example

For `x = 2, y = 3, z = 2`, the output should be `23`

`23 % 3 = 2, 23 % 5 = 3, 23 % 7 = 2`

For `x = 1, y = 2, z = 3`, the output should be `52`

`52 % 3 = 1, 52 % 5 = 2, 52 % 7 = 3`

For `x = 1, y = 3, z = 5`, the output should be `103`

`103 % 3 = 1, 103 % 5 = 3, 103 % 7 = 5`

For `x = 0, y = 0, z = 0`, the output should be `105`

For `x = 1, y = 1, z = 1`, the output should be `1`

# Note

- `0 <= x < 3, 0 <= y < 5, 0 <= z < 7`

- Happy Coding `^_^`
