- A single statement that declares a variable and specifies array values as its content is called an array Select one: a.literal b.constructor C.element d.index23. True or False: The bracket of the array type can be associated with the element type or with the name of the array. float[] prices; -> float prices[]; False True Give an explanation for the answer. Thank youInput Parameters: sea: an array of integers indices': an array of integers (each of which may or may not be a valid index for sea") Assumptions: sea may be empty. indices may be empty. *indices may contain duplicates. What to return? - For each integer value in 'indices', if it is a valid index for input array ssa', then use it to index into 'sea' and include the result in the output array. For example: Say ssa' is (23, 46, 69} and indices' is (2, -1, 0, 3, 0, 2} (where indices -1 and 3 are invalid, so only indices 2, 0, 0, 2 are used) Then the method should return (69, 23, 23, 69} Note: Order of elements in the output array corresponds to the order in which valid indices in the 'indices' array are arranged. That is, the output array may be empty if the input array sea is empty, or if the input array indices does not contain any valid indices. See the JUnit tests related to this method. */ public static int () task1(int ) seq, int () indices) { int (] result - null; return result;
