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
• Repetition 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

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).

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).

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).

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).
