Why [], 0, 0 should return False?

The question reads
find out whether there are two distinct indices i and j in the array
such that the difference between nums[i] and nums[j] is at most t and
the difference between i and j is at most kand there are NO such two distinct indices in an empty array can satisfy the requirement, therefore should return false
(Similarly, an array with only 1 element would never satisfy the requirement, either.)
