## Python Run-Length Encoder
A RunLengthEncoder class with 3 available methods, all of which take an input string and return a compressed output string.
Examples:
- `encode_a`
```py3
from run_length_encoder import RunLengthEncoder
encoder = RunLengthEncoder()
result = encoder.encode_a("abc123xyzaaabbbcccd")
print(result)
```
`encode_a` Returns a compressed string from an input string.
Note: This function will not return the character count in the return string if only a single instance of the character is found.
Result:
```sh
abc123xyz3a3b3cd
```
- `encode_b`
```py3
from run_length_encoder import RunLengthEncoder
encoder = RunLengthEncoder()
result = encoder.encode_b("abc123xyzaaabbbcccd")
print(result)
```
`encode_b` Returns a run-length encoded string from an input string, with a count for each character, followed by the character itself.
Result:
```sh
1a1b1c1112131x1y1z3a3b3c1d
```
- `encode_c`
```py3
from run_length_encoder import RunLengthEncoder
encoder = RunLengthEncoder()
result = encoder.encode_c("abc123xyzaaabbbcccd")
print(result)
```
`encode_c` uses a list comprehension to build the return string.
Result:
```sh
1a1b1c1112131x1y1z3a3b3c1d
```
