Assume a full associative cache which can allocate up to 4 blocks. The next sequence of block references are generated by the processor:

Block references -->400, 1006, 577, 679, 2086, 1006, 577, 1544, 1006, 186

After the fourth reference, the state of the cache is: cache block content

block 0 --> block 400 of MM

block 1 --> block 1006 of MM

block 2 --> block 577 of MM

block 3 --> block 679 of MM

What block of MM will be in the block 0 of the cache after the last reference (186)?
