Program to find the frequency of each element of an array is discussed here. Given an array, the task is to find the frequency of all the elements of the array.

For example, consider the following array

**Input:**

arr = {1, 2, 3, 5, 2, 9, 7, 3, 5}

**Output:**

1 occurs 1 times

2 occurs 2 times

3 occurs 2 times

5 occurs 2 times

7 occurs 1 times

9 occurs 1 times

- Input the number of elements of an array.
- Input the array elements.
- Create another array to store the frequency of elements.
- Traverse the input array and update the count of the elements in the frequency array.
- Print the frequency array which displays the frequency of all the elements of the array.

Output

Input -
Enter the number of elements : 6
Enter elements in array :
1
2
3
1
2
6
Output -
1 occurs 2 times
2 occurs 2 times
3 occurs 1 times
6 occurs 1 times

- Input the number of elements of the array.
- Input the array elements.
- Create a hash table and update the element in one column and its frequency in the other column.
- Print the element along with its frequency.
