# Instructions

Your task is to count the number of 1 bits in the binary representation of a number.

## Restrictions

Keep your hands off that bit-count functionality provided by your standard library!
Solve this one yourself using other basic tools instead.

# Introduction

Your friend Eliud inherited a farm from her grandma Tigist.
Her granny was an inventor and had a tendency to build things in an overly complicated manner.
The chicken coop has a digital display showing an encoded number representing the positions of all eggs that could be picked up.

Eliud is asking you to write a program that shows the actual number of eggs in the coop.

The position information encoding is calculated as follows:

1. Scan the potential egg-laying spots and mark down a `1` for an existing egg or a `0` for an empty spot.
2. Convert the number from binary to decimal.
3. Show the result on the display.

Example 1:

```text
Chicken Coop:
_ _ _ _ _ _ _
|E| |E|E| | |E|
Resulting Binary:
1 0 1 1 0 0 1
Decimal number on the display:
89
Actual eggs in the coop:
4
```

Example 2:

```text
Chicken Coop:
_ _ _ _ _ _ _ _
| | | |E| | | | |
Resulting Binary:
0 0 0 1 0 0 0 0
Decimal number on the display:
16
Actual eggs in the coop:
1
```
