Write the method is PreviousIndex, which will receive two parameters. The first one is an array of integer numbers, and the other one is an integer value as an index. The method should return a true boolean value only if the number at the index received as the second parameter appears in a previous element than the index received as second parameter). It should return false otherwise. As an example, if the array received was the following: int[] numbers - (3, 4, 5, 6, 7, 8, 4, 6, 2, 7, 8, 9, 1, 2, 2, , 7, 7); With an integer 6 as the index. It should return true given that the number 4 is also at index 1. However, if the number received as index was 1 it should return false, since the value 4 does not appear at any Index previous than 1. In other words, the index O in that array is not the same as the one in the index 1. Note that you only need to code the method, not all the program.
