/*

* is equal to (or balances) the sum of values[index+1 .. length-1]
|
|

* look at the examples below
|
|
||||||
* Your task: design and code the canBalance methods that returns true or false
|
|
||||||
* the program should be efficient.
|
|

* can you solve the problem without using nested loops? 1 loop? 2 loops?
|
|

* Then run the program to see if your method works correctly.
