Most frequent element in an array in C++

[ayush-1909]

I wanna add most frequent element in an array in C++ in the DSA directory.

Kindly assign it to me.

you can have a look at the code.

#include <bits/stdc++.h>
using namespace std;

int mostFreq(int arr[], int n)
{
// Sorting
sort(arr, arr + n);

// using linear traversal
int max_count = 1, res = arr[0], curr_count = 1;
for (int i = 1; i < n; i++) {
    if (arr[i] == arr[i - 1])
        curr_count++;
    else {
        if (curr_count > max_count) {
            max_count = curr_count;
            res = arr[i - 1];
        }
        curr_count = 1;
    }
}

// if most freq = last element
if (curr_count > max_count)
{
    max_count = curr_count;
    res = arr[n - 1];
}

return res;

}

int main()
{
//array
int arr[] = { 1, 7, 2, 3, 3, 2, 3 };
int n = sizeof(arr) / sizeof(arr[0]);
cout << mostFreq(arr, n);
return 0;
}
