Answer:
If there is a majority element in the array it will be the median. Thus,
just run the linear time median finding algorithm, and compare the result with all the elements of the array (also linear time). If
elements are the same as the median, the median is a ma majority element. If not, there is none.
Suppose now that the elements of the array are not from some ordered domain like the integers, and so there can be no comparisons of the form "is the ith element of the array greater than the jth element of the array?" However you can answer questions of the form:
"Are the ith and jth elements of the array the same?" in constant time. Such
queries constitute the only way whereby you can access the array. (Think of the elements of the array as GIF files, say.) Notice that your solution above cannot be used now.
Answer:
Breaking it down I guess for me, you could take down all the possible things that you could do. Eliminating things, one by one. It could help working on a computer by not letting yourself get over-whelmed by all your programming and thinking "alright, this THEN this."
