Boyer–Moore majority vote algorithm

Boyer–Moore majority vote algorithm

%% Boyer–Moore majority vote algorithm
% The Boyer-Moore Vote Algorithm solves the majority vote problem in
% linear time O(n) and logarithmic space O(\log n). The majority vote
% problem is to determine in any given sequence of choices whether
% there is a choice with more occurrences than all the others, and if so,
% to determine this choice. Mathematically, given a finite sequence
% (length n) of numbers, the object is to find the majority number
% defined as the number that appears more than floor(n/2) times.%
%
% Example:
%
% consider we want to find the majority element in 'aaaccbbcccbcc'
% MajorityVote('aaaccbbcccbcc')
% ans =
% c
