PROGRAMMING:C language experiment odd even bit exchange

Input a 0,1 string to realize the parity bit exchange of the string. The first bit is calculated from the right side of the string.
###Input format:
First, we give a C, which means there are several groups of test data
Each group of data input is 0,1 string, ensure that the string length is even (< = 50)
###Output format:
Each group of data output a parity bit interchangeable 0,1 string.
###Input example:
Here is a set of inputs. For example:
```in
two
0110
one thousand and one hundred
```
###Output example:
The corresponding output is given here. For example:
```out
one thousand and one
one thousand and one hundred
```
