#include <stdio.h>
int main()

    int num,i,j;
    printf("Enter the number of elements in the array : ");
    scanf("%d",&num);
    int arr[num];
    printf("Enter the elements of the array : ");
    for(i=0;i<num;i++)
    {
        scanf("%d",&arr[i]);
    }
    int frequency[num];
    int visited = -1;


    for(i = 0; i < num; i++)
    {
        int count = 1;
        for( j = i+1; j < num; j++)
        {
            if(arr[i] == arr[j])
            {
                count++;
                frequency[j] = visited;
            }
        }
        if(frequency[i] != visited)
        {
            frequency[i] = count;
        }
    }
    printf("Element  Frequency\n");
    for(i = 0; i < num; i++)
    {
        if(frequency[i] != visited)
        {
            printf("%d \t : %d \n", arr[i], frequency[i]);
        }
    }
    return 0;
