Implement a function dropRightWhile(array, predicate) that removes elements from the end of an array until the predicate returns false.

• array: The array to iterate over.
• predicate: A function invoked with each element, index, and the whole array. Stop dropping when predicate returns false.

Example

dropRightWhile([1, 2, 3, 4], n => n > 2); // [1, 2]
dropRightWhile([1, 2, 3, 4], n => n < 4); // [1, 2, 3, 4]
