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[] = {...
PHP array_count_values() function counts the occurrences of all values in an array and returns an associative array formed by the unique value of input array as keys, and the number of their occurrences in the array as values. In this tutorial, we will learn the syntax of array_count_val...
To count the number of occurrences of a specific value in given array in PHP, we can usecount()andarray_filter()functions. array_filter()function is used to filter only the elements that match given value, and thencount()is used to find the number of values in the filtered array. The ...
This function counts the occurrences of all elements in an array. It uses the reduce() method to iterate over the array and increment a count for each unique element, returning an object with each element and its count. JavaScript: let countElements = arr => arr.reduce((acc, val) => ...
