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) …
WebQuestion: Write C++ code to solve the following problem: Given an array of n integers, find the first element that occurs k number of times. If no element occurs k times, print -1. Use a map to solve the problem. Example 1: Input: {1, 7, 4, 3, 4, 8, 7} and k = 2 Output: 4 Explanation: Both 7 and 4 occur 2 times, but 4 is the first that occurs 2 times.
