The majority element of a subarray is an element that occursthresholdtimes or more in the subarray. Implementing theMajorityCheckerclass: MajorityChecker(int[] arr)Initializes the instance of the class with the given arrayarr. int query(int left, int right, int threshold)returns the element in ...
Amajority elementis an element that appears more thanN/2times in an array of lengthN. Example 1: Input: nums =[2,4,5,5,5,5,5,6,6], target =5 Output:true Explanation: The value 5 appears 5 times and the length of the array is 9. Thus, 5 is a majority element because 5 > ...
MajorityChecker(int[] arr) Initializes the instance of the class with the given array arr. int query(int left, int right, int threshold) returns the element in the subarray arr[left...right] that occurs at least threshold times, or -1 if no such element exists. Example: Example 1: In...
The majority element is the element that appears more than⌊n / 2⌋times. You may assume that the majority element always exists in the array. Example 1: Input: nums = [3,2,3] Output: 3 Example 2: Input: nums = [2,2,1,1,1,2,2] ...
