In an Additional-Reference-Bits LRU Approximation Algorithm, each page has an 8-bit shift register. The bit associated with each page referenced is set (to 1) by the hardware. These 8-bit shift registers contain the history of page use for the last eight time periods. The register value of the 8 pages are as given: 1. 00100010 2. 11000100 3. 00010111 4. 11100111 5. 11110111 6. 10000011 7. 01010111 8. 00000011 Which page will be replaced by the LRU Approximation Algorithm last? Which page will be replaced by the LRU Approximation Algorithm first?
