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. From here. Following is an interesting O(nk) solution: We can solve the above problem in O(nk) time using O(k-1) … WebGiven an array of N integers. Find the first element that occurs at least K number of times. Example 1: Input : N = 7, K = 2 A[] = {1, 7, 4, 3, 4, 8, 7} Output : 4 Explanation: …
algorithm - Find an element that occurs at least k times in …
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 ...

WebMay 21, 2024 · Efficient Approach: Use unordered_map for hashing as the range is not known.Steps: Traverse the array of elements from left to right. While traversing increment their count in the hash table. Again traverse the array from left to right and check which … elements() is one of the functions of Counter class, when invoked on the … WebThe frequency of an element is the number of times it occurs in an array.. You are given an integer array nums and an integer k.In one operation, you can choose an index of nums and increment the element at that index by 1.. Return the maximum possible frequency of an element after performing at most k operations..
