Determine for the following code how many pages are transferred betu'een disk and main rnemory, assuming each page has 512 words, the active memory set size is 256 (i. e., at any time no more than 256 pages miiy be in main memory), and the replacement strategy is LRU (the Least Recently Used page is always replaced); also assume that all two-dimensional arrays are of size (1 :1024, I:1024), with each array element occupying one word,

for I := 1 to 1024 do

for J : =1 to 1024 do

{ A[I;J] = A[I,J] *B[J,I] ]

provided the arrays are mapped into the main memory space in column-major order,
