Given a string with a number for example: 0100243170112001410001

Task: seperate the string into blocks of 2 and 4 characters. Your blocks shouldnt start with 0 unless its not possible to do it different.

Example output (more possible solutions):
0100-2431-70-11-200-14-100-01

Note: spliting the beginning into 2char blocks could be needet to make it work at the end of the string.
