👉 In computer science, a splicer is a function that takes an array of integers and returns an array with each element duplicated. This operation is often used in algorithms to create a new array by appending elements from another array. For example, in the following code: ``` int[] arr = {1, 2, 3}; int[] result = Arrays.copyOf(arr, arr.length); Arrays.fill(result, arr[0]); System.out.println(Arrays.toString(result)); ``` The splicer function
