Don't handle every array item within each array item - #4480
Merged
Conversation
In handleArray, the array v is looped over. For each item, the entire array is looped over again, resulting in an array v of length n resulting in an output array of length n^2, making handleArray's complexity O(n^2). However, that n^2 looping is unnecessary. Removing it brings the complexity of handleArray down to O(n), drastically reducing execution time.

… of the spurious results either cause they're not there in the first place - this should also speed up processing since we don't need to do a jillion searches Signed-off-by: Amndeep Singh Mann <amann@mitre.org>
…dn't realize - the original zap sample has a duplicate subfinding for some reason and we were removing it from our results through the dedupe process. now it's put back and correctly reflects the original file Signed-off-by: Amndeep Singh Mann <amann@mitre.org>

Excellent catch. Extended the implication from where you found savings with my own commits.
