WebThe Boyer-Moore voting algorithm is used to find the majority element among the given elements that have more than N/2 occurrences. This algorithm works on the fact that if an element occurs more than N/2 times, it means that the remaining elements other than this would definitely be less than N/2. WebJan 20, 2024 · Algorithm : Loop through each element and maintain a count of majority element, and a majority index, max_index. If the next element is same then increment the count if the next element is not same then decrement the count. if the count reaches 0 then changes the max_index to the current element and set the count again to 1.
