What this does

Finds frequency of the unique elements present in a list (Array or Vector).

It returns a hashmap, with each unique item and its frequency as key:value pair.

Features:

1. Parallel frequency counting. List items are equally distributed in each logical threads.
2. Fast hashing algorithm (XxHash).
3. Expressive and clean code.

Efficiency

Time Complexity: O(N) Space Complexity: O(N)

Version Note: Performance improvement and change in api.

User Guide

This crate exports a function frequency_finder. It takes a slice as parameter, that means you can pass a slice to an Array or Vector. It will return a hashmap that will contain each unique item and its frequency as key value pair.

Quick Start

```rust use elementsfrequency::interface::frequencyfinder;

fn main () { let myList = [1, 1, -6, 2, 6, 2, 7, 1];

let frequency_map = frequency_finder(&myList);

println!("{:?}", frequency_map);

// Output:

// { 2: 2, 1: 3, -6: 1, 7: 1, 6: 1 }

} ```
