Interval Coverage Count

Problem

Count how many actual values fall inside their corresponding prediction interval, i.e. lower[t] <= actual[t] <= upper[t].

Return the count as an integer.

Hint

Both bounds are inclusive, so values exactly on a limit still count.

case 1

in: [[1,2,3],[0,1,2],[2,3,4]]

expected: 3

case 2

in: [[5,5,5],[1,2,3],[4,4,4]]

expected: 0

case 3

in: [[0,10],[0,10],[0,10]]

expected: 2

case 4

in: [[1,2,3],[1,1,1],[3,3,2]]

expected: 2
