   1 flagged finding: an anonymous unverified quote attributed to an unverifiable 'Software Engineer, Google, discussing interview preparation.'

   Before

   "The single most important complexity optimization pattern in interviews is: if you have a nested loop where the inner loop does a search or comparison, ask yourself if that search or comparison can be precomputed into a hash map. This takes you from O(n^2) to O(n) in dozens of interview problems." - Software Engineer, Google, discussing interview preparation

   After

   The single most important complexity optimization pattern in interviews is this: if you have a nested loop where the inner loop does a search or comparison, ask yourself if that search or comparison can be precomputed into a hash map. This takes you from O(n^2) to O(n) in dozens of interview problems.

   Why: Removed an unverified quote incorrectly attributed to an unverifiable 'Software Engineer, Google, discussing interview preparation' and converted it to unattributed prose preserving the underlying claim.
