Lab 5
Task 1
After fiddling around, I managed to get it to compile using MinGW on windows. What does the results mean? Who knows? LOL
gcc -o lab5 arraylist.c buzhash.c randtest.c lab-5.c
Results
This is the first output I got.
Testing Buzhash low on 1000 samples Entropy = 7.843786 bits per byte. Optimum compression would reduce the size of this 1000 byte file by 1 percent. Chi square distribution for 1000 samples is 214.46, and randomly would exceed this value 95.00 percent of the times. Arithmetic mean value of data bytes is 128.0860 (127.5 = random). Monte Carlo value for Pi is 3.132530120 (error 0.29 percent). Serial correlation coefficient is -0.017268 (totally uncorrelated = 0.0). Buzhash low 50/1000: llps = 1, expecting 1.72187
