Method 1 (Linear Search) Linearly search for x, count the occurrences of x and return the count. Time Complexity: O(n) Method 2 (Use Binary Search) 1) Use Binary search to get index of the first occurrence of x in arr[]. Let the index of the first occurrence be i. 2) Use Binar...
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 > ...
