Problem 555. "Low : High - Low : High - Turn around " -- Create a subindices vector
Let two vectors lo and hi be given.
The job is to create a index vector like so
idx = [lo(1):hi(1) lo(2):hi(2) ...]
Where : is the colon operator.
One can assume that all entries are positve integers. Delete all pairs where lo(i) > hi(i).
For example:
- lo = [1 5 10]; hi = [3 8 12];
idx = [1 2 3 5 6 7 8 10 11 12]
- lo = [3 5 6 7]; hi = [1 4 6 8];
idx = [6 7 8]
