Hardware interview practice
Classify an address range
Return LOW for [0:16], MED for [17:127], HIGH for [128:256], and OUT otherwise.
Reviewed example
Work through one case
Input
unsigned addresses=[0,16,17,127,128,256,257]Expected output
classes=[LOW,LOW,MED,MED,HIGH,HIGH,OUT]Both endpoints of each legal interval are inclusive, adjacent class boundaries have no gap or overlap, and 257 is above the highest legal address.
What to cover
Requirements
- Treat all interval endpoints as inclusive.
- Represent OUT explicitly.
- Avoid gaps or overlaps.
