Find element to occur k times

WebMay 28, 2024 · There is a variation of Boyer-Moore Voting algorithm which can find all the elements that occurs more than n/k in a input which runs in O(nk) and since k = 10 for your problem I think it should run in O(n * 10) = O(n) time.

WebThe idea is that max no. elements are 26. So, we don't have to check all the substrings, we just have to check substrings with length<=26*k (26*k length is the case when all elements will occur k times. If length is more than that then at least one element will have to occur at least k+1 times). Also, we need to check only those substrings ...
