WebApr 10, 2024 · A Simple Solution is to run two nested loops. The outer loop picks all elements one by one and the inner loop counts the number of occurrences of the element picked by the outer loop. The time complexity of this solution is O (n 2 ). Below is the implementation of the brute force approach : C++ Java Python3 C# PHP Javascript … 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.. Example 1: Input: nums = [1,2,4], k = …
