The main element of a data series is the element in the sequence that occurs more than half the length of the sequence.Method 1 (Expected time complexity is O (n)):Because the main element occurs more than half the length of the sequence, the main element must be the median. Recursive partitioning can be used to find the median, and the expected time complexity i
