The Cartesian product (or cross product) of two sets, S1 and S2, is often denoted by the symbol × and is defined follows: S1×S2 = {(x, y) | x ∈ S1∧y ∈ S2}. Using tuple and list notation, write a function called cross Product: 0a list ∗ 0b list → (0a ∗ 0b) list that takes two lists as input and returns their Cartesian product

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
