compare two arrays.

[Byak@]

how can i fast compare two arrays?arrays have one and big(300000) langth.
i'm use

diff=false
for i=0 to arraylen(arr1())-1
if arr1(i)<>arr2(i) then
diff=true
exit
end if
next

array.count

Hi
diff=false
if arr1.count<>arr2.count then
diff =true

Will this do?

arrays have one and big(300000) length.

arrays have same count, i want compare elements.
i'm found a fast way (for arrays of bytes only)

bitwise.new2(1252)
if strcompare(bitwise.bytestostring(arr1(),0,arraylen(arr1())),bitwise.bytestostring(arr2(),0,arraylen(arr2())))<>0 then diff=true

this code do at 30ms for arrays with 300000 elements

Sarcasm?

 

[nick2210]

no sarcasm

No sarcasm at all.
I also hope that your line of code above will help me in better understanding the whole bitwise stuff.
P.S. Failed to send you a message via ICQ.:sign0089:
