You can count the occurrences of an array of elements by creating an object. Afterward, you add the array elements to the object using afor...ofloop. During thefor...ofloop, you check if the element is already in the object; if so, you increment its value by one. Otherwise, it’s...

Theforloop is one of the standard methods to loop through an array. It allows us to loop over each element of an array and compare it to the element we are looking for. That way, we can count the number of occurrences of that element in an array. We can also use it to count the...
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[] ...

Let's say we are going to find out number of occurrences of a number in a sorted array using binary search in O(log n) time. For example the given array is: [1,1,3,5,5,5,5,5,9,11], the number 5 appears 5 times;
Method 1 – Number of Occurrences of a Particular Date 1.1 Using the COUNTIF Function Steps: Select cell E5. Enter the following formula: =COUNTIF(C5:C243,"18-Aug-1888") Press Enter. 1.2 Using the SUMPRODUCT Function Steps: Select cell E5. Enter the following formula: =SUMPRODUCT(--(...
