In computer science, inclusive/exclusive doesn’t apply to algorithms, but to a number range (more specifically, to the endpoint of the range):
1 through 10 (inclusive)
1 2 3 4 5 6 7 8 9 10
1 through 10 (exclusive)
1 2 3 4 5 6 7 8 9
In mathematics, the two ranges above would be:
[1, 10]
[1, 10)
You can remember it easily:
- Inclusive – Including the last number
- Exclusive – Excluding the last number
