title: How to compare two arrays in delphi and remove duplicates from one
body: <p>I have two arrays. Array1 is holding medical terminologies while array2 is holding plain english terminologies. The medical terminology array has some non-medical english words in it (which are duplicated in array1). These are 20,000 in array1 and over 15000 in array2. What is the fastest way of comparing the two arrays and remove the duplicate words from array1 using delphi?</p>
