You are given an array nums consisting of positive integers.Return the total frequencies of elements in nums such that those elements all have the maximum frequency.The frequency of an element is the number of occurrences of that element in the array. Example 1:Input: nums = [1,2,2,3,1,4]Output: 4Explanation: The elements 1 and 2 have a frequency of 2 which is the maximum frequency in the array.So the number of elements in the array with maximum frequency is 4
Question
You are given an array nums consisting of positive integers.Return the total frequencies of elements in nums such that those elements all have the maximum frequency.The frequency of an element is the number of occurrences of that element in the array. Example 1:Input: nums = [1,2,2,3,1,4]Output: 4Explanation: The elements 1 and 2 have a frequency of 2 which is the maximum frequency in the array.So the number of elements in the array with maximum frequency is 4
Solution
To solve this problem, you can follow these steps:
-
Create a dictionary to store the frequency of each number in the array. You can do this by iterating over the array and for each number, if it is not in the dictionary, add it with a value of 1. If it is already in the dictionary, increment its value by 1.
-
Find the maximum frequency in the dictionary. You can do this by iterating over the values in the dictionary and keeping track of the maximum value.
-
Count the number of elements in the dictionary that have the maximum frequency. You can do this by iterating over the values in the dictionary and incrementing a counter each time you find a value equal to the maximum frequency.
-
Return the counter.
Here is a Python code that implements these steps:

Frequency of all NumbersWrite a Program to print all the frequencies in a given an Array.Constraints:First line consists an integer representing the length of the array(n).Length of the array must be greater than zero or else Print Invalid Input.Second line consists all the Elements of an array.All the Elements in the array must be greaterthan zero or else print Invalid Input.Example:Input 1 : 6 1 2 2 3 3 3Output 1 : 1 - 1 2 - 2 3 - 3Input 1 : -6Output 1 : Invalid Input
Given an array arr[] of n positive integers which can contain integers from 1 to p where elements can be repeated or can be absent from the array.Your task is to count the frequency of all numbers from 1 to n. Do modify the array in-place changes in arr[], such that arr[i] = frequency(i) and assume 1-based indexing.Note: The elements greater than n in the array can be ignored for counting. ExamplesInput: n = 5 arr[] = {2, 3, 2, 3, 5} p = 5Output: 0 2 2 0 1Explanation: Counting frequencies of each array element We have: 1 occurring 0 times. 2 occurring 2 times. 3 occurring 2 times. 4 occurring 0 times. 5 occurring 1 time.Input: n = 4 arr[] = {3,3,3,3} p = 3Output: 0 0 4 0Explanation: Counting frequencies of each array element We have: 1 occurring 0 times. 2 occurring 0 times. 3 occurring 4 times. 4 occurring 0 times.Input: n = 2 arr[] = {8,9} p = 9Output: 0 0Explanation: Counting frequencies of each array element We have: 1 occurring 0 times. 2 occurring 0 times. Since here P=9, but there are no 9th Index present so can't count the value.Your Task:You don't need to read input or print anything. Complete the function frequencyCount() that takes the array arr, and integers n, and p as input parameters and modify the array in-place to denote the frequency count of each element from 1 to N.Expected time complexity: O(N)Expected auxiliay space: O(1)Constraints:1 ≤ n ≤ 1051 ≤ p ≤ 4*104 1 <= arr[i] <= p
You are given an array of positive integers nums.Return the number of subarrays of nums, where the first and the last elements of the subarray are equal to the largest element in the subarray. Example 1:Input: nums = [1,4,3,3,2]Output: 6Explanation:There are 6 subarrays which have the first and the last elements equal to the largest element of the subarray:subarray [1,4,3,3,2], with its largest element 1. The first element is 1 and the last element is also 1.subarray [1,4,3,3,2], with its largest element 4. The first element is 4 and the last element is also 4.subarray [1,4,3,3,2], with its largest element 3. The first element is 3 and the last element is also 3.subarray [1,4,3,3,2], with its largest element 3. The first element is 3 and the last element is also 3.subarray [1,4,3,3,2], with its largest element 2. The first element is 2 and the last element is also 2.subarray [1,4,3,3,2], with its largest element 3. The first element is 3 and the last element is also 3.Hence, we return 6.Example 2:Input: nums = [3,3,3]Output: 6Explanation:There are 6 subarrays which have the first and the last elements equal to the largest element of the subarray:subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.subarray [3,3,3], with its largest element 3. The first element is 3 and the last element is also 3.Hence, we return 6.Example 3:Input: nums = [1]Output: 1Explanation:There is a single subarray of nums which is [1], with its largest element 1. The first element is 1 and the last element is also 1.Hence, we return 1. Constraints:1 <= nums.length <= 1051 <= nums[i] <= 109
