A system uses a fixed allocation of FIVE physical memory frames

A system uses a fixed allocation of FIVE physical memory frames and the following reference string over seven pages: 1, 2, 3, 4, 2, 1, 5, 6, 2, 1, 2, 3, 7, 5, 2, 3, 6. Assuming memory starts empty, how many page faults will occur and what will be the final contents of memory under the LRU page replacement policy? 141
