Suppose the block size of the cache in the processor is 4096 bytes. The ASCII value of the characters 'a' through 'z' is 97 through 122. Suppose previously array2[99*4096] was loaded into the cache. Now we write a program that accesses array2[k*4096] and measures the time it takes to access the value, with k varying from 97 to 122. Why can you expect the access time to array2[k*4096] be lower for k=99 than others?
