First element occurring k times in an array
WebApr 12, 2024 · We use following steps to find occurrence-. First we create an unsorted_map to store elements with their frequency. Now we iterate through the array and store its elements inside the map. Then by using map.find () function, we can easily find the occurrences (or frequency) of any element. Below is the implementation: WebJun 23, 2015 · The idea is, you check the element at index i+k-1, if it matches the element at index i - good, it's a dupe.

WebApr 11, 2024 · Naive Approach: The simplest approach to solve this problem is to traverse the array and for every distinct array element, count its frequency and check if exceeds N / K or not. If found to be true, then print the array element. Time Complexity: O(N 2) Auxiliary Space: O(1) Sorting-based Approach: The idea is to sort the array followed by traversal … WebStep 1: Create a hash map, where key is the element and value is the frequency of occurrence of that element in the input array. Step 2: Using a loop, iterate over the elements and increase its value by 1 in the hash map created in the previous step. Step 3: Set the len as the 'MAP.SIZE'.
