Problem
A sample of 121 integers is given, each between 1 and 1000 inclusive, with repetitions allowed. The sample has a unique mode (most frequent value). Let 
be the difference between the mode and the arithmetic mean of the sample. What is the largest possible value of 
? (For real 
, 
is the greatest integer less than or equal to .)
