initialize collection word-frequency
for each document
 for each word in the document
   if the word exists in word-frequency
     bump frequency
   else
     add the word to word-frequency with frequency 1

initialize top-frequency to 0, top-word to null
for each word in word-frequency
 if its frequency is greater then top-frequency
   assign the frequency to top-frequency, word to top-word

the top-word is the word that repeats most

tHere are two most commonly used:

1. sort and look for adjacent duplicates.

2. build a HashSet.  If word is already in there, you have a dup.
