# Task

Write a program that takes a positive number (`num`) and finds the power of $2$ nearest to that number. The program stores the resulting value to `pwr`.

If there are two candidate values, display the smaller one. For example, $2$ and $4$ are both the powers of $2$ nearest to $3$. The function should display $2$ because it's smaller than $4$.

---

## Sample input 1
```t
num = 40
``` 
## The resulting value 1
```t
pwr = 32
```
## Expected output 1
```t
The 32 is the power of 2 nearest to 40.
```

---

## Sample input 2
```t
num = 50
``` 
## The resulting value 2
```t
pwr = 64
```
## Expected output 2
```t
The 64 is the power of 2 nearest to 50.
```

## How to test your program
When you click the "Test" button under the code widget, you'll get the two options explained below:

* **Show Results:** It shows the sample inputs and their respective results in comparison with the expected output. The actual output is the power calculated to display the results. The word "Succeeded" in the last column indicates that the calculated output matches the expected output. For example, if `num` is `50` and the `pwr` is `64`, then the last column shows "Succeeded".

* **Show Console:** It shows the output from the `console.log()` statements used in your code. You may use this to verify your calculations on the basis of sample test inputs. For example, if `num` is `50`, then the output on the console should be `The 64 is the power of 2 nearest to 50.`.

Find the nearest power of 2 for a number that has been input.
