Consider a system processing two text sequences of different lengths in a single batch. To create a uniform input, the shorter sequence is extended with special ⟨pad⟩ tokens. A visualization of the system's memory reveals that the data blocks for these sequences are stored in non-contiguous physical locations, with gaps of unused memory between them. What is the primary operational challenge illustrated by this non-contiguous storage arrangement?
