The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help. Parameters: array - leftRotation - positions - Throws:java.lang.IllegalArgumentException - When a null array parameter is provided
