Hello,
I have a programming questions to you all,
I have three arrays: arrayA1, arrayA2, (arrayA1 and arrayA2 are same
length) and array B. Using the following code I created the fourth
arrayC that contain intersection elements between arrayA1 and arrayB.
Now I need to get the corresponding elements in arrayA2 into arrayD.
Can anyone help me with this issue?
map { $original {$_} = 1 } @arrayA1;
@arrayC = grep {$original {$_} } @arrayB;
The bottom line question is how to track the element location of $_ in
arrayA1 when generating the intersected elements in arrayB, then use
this index to get
the corresponding elements in arrayA2.
Thanks in advance for your help and have a good night!
AG Lee
