* Input Parameters: * - seg: an array of integers * indices': an array of integers (each of which may or may not be a valid index for "seg") * Assumptions: * seg 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 `seq' then use it to index into `seq' and include the result in the output array. For example: Say `seq' 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 `seg 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; * 7* Your task is to implement this method, * so that running TestUtilities.java will pass all JUnit tests. * Recall from Week 1's tutorial videos: * 1.

For example, {2, 4, 1, 3} encodes that value 2 (at even index () should repeat 4 times (as specified at odd index 1), and similarly, value 1 should repeat 3 times. Say `seq' is {2, 2, 2, 2, 1, 1, 1}.
