C++ program to count number of occurrences (or frequency) in a sorted array#include <bits/stdc++.h> using namespace std; //naive approach void findFrequencyeNaive(vector<int>& arr, int num) { int d; cout << "...Using naive search...\n"; //O(n) time complexity int freq =...
Given a sorted array arr[] and a number x, write a function that counts the occurrences of x in arr[]. Expected time complexity is O(Logn) Examples: Input: arr[] = {1, 1, 2, 2, 2, 2, 3,}, x = 2 Output: 4 // x (or 2) occurs 4 times in arr[] Input: arr[] = {...
