Example program printout
------------------------
Frame print format: "frames: frame-num:[process-num:page] ..."
Clock algorithm data format: "clock: frame0-A - frame1-A ..."
In the following example offset is 8-bit wide (last 2 hex digit of address).

process 3 READ LA=0x0234
frames: 0:[2:0] 1:[1:2] 2:[1:3] 3:[3:0] 4:[2:3] 5:[3:1] 6:[3:2] 7:[1:0]
HIT:                                                    ^^^^^^^
paging: process 3, page=2 => frame=6, 0x0234 => 0x0634
read value at 0x0645 => 0x42       (0x42 must be written there before!)
clock: 0-0-0-1-0-0-1-1
hand         ^

process 2 WRITE(0x73) LA=0x0321
frames: 0:[2:0] 1:[1:2] 2:[1:3] 3:[3:0] 4:[2:3] 5:[3:1] 6:[3:2] 7:[1:0]
HIT:                                    ^^^^^^^
paging: process 2, page=3 => frame=4, 0x0321 => 0x0421
save (0x73) at 0x0421
clock: 0-0-0-1-1-0-1-1
hand         ^

process 1 WRITE(0x37) LA=0x0101
frames: 0:[2:0] 1:[1:2] 2:[1:3] 3:[3:0] 4:[2:3] 5:[3:1] 6:[3:2] 7:[1:0]
MISS (page 1 not in memory)
clock before: 0-0-0-1-1-0-1-1
hand before:        ^
clock after:  0-0-0-0-0-0-1-1
hand after:             ^
use frame 5:
- save to disk:   process 3, page 1
- load from disk: process 1, page 1
frames: 0:[2:0] 1:[1:2] 2:[1:3] 3:[3:0] 4:[2:3] 5:[1:1] 6:[3:2] 7:[1:0]
restarting instruction:

paging: page=1 => frame=5, 0x0101 => 0x0501
save (0x37) at 0x0501
clock:  0-0-0-0-0-1-1-1
hand:             ^

process 1 WRITE(0x37) LA=0x0701
