Introduction and Warm-up (Highly recommended)
Playing With Lists/Arrays Series
Definition
An element is leader if it is greater than The Sum all the elements to its right side.

Task
Given an array/list [] of integers , Find all the LEADERS in the array.

Notes
Array/list size is at least 3 .

Array/list's numbers Will be mixture of positives , negatives and zeros

Repeatition of numbers in the array/list could occur.

Returned Array/list should store the leading numbers in the same order in the original array/list .

Input >> Output Examples
1 - arrayLeaders ({1, 2, 3, 4, 0}) ==> return {4}
Explanation:
4 is greater than the sum all the elements to its right side

Note : The last element 0 is equal to right sum of its elements (abstract zero).

2- arrayLeaders ({16, 17, 4, 3, 5, 2}) ==> return {17, 5, 2}
Explanation:
17 is greater than the sum all the elements to its right side

5 is greater than the sum all the elements to its right side

Note : The last element 2 is greater than the sum of its right elements (abstract zero).

3- arrayLeaders ({5, 2, -1}) ==> return {5, 2}
Explanation:
5 is greater than the sum all the elements to its right side

2 is greater than the sum all the elements to its right side

Note : The last element -1 is less than the sum of its right elements (abstract zero).

4- arrayLeaders ({0, -1, -29, 3, 2}) ==> return {0, -1, 3, 2}
Explanation:
0 is greater than the sum all the elements to its right side

-1 is greater than the sum all the elements to its right side

3 is greater than the sum all the elements to its right side

Note : The last element 2 is greater than the sum of its right elements (abstract zero).
