What I did in this code was that I created a static variable = index which stored the starting index ( si ) for each function call under the condition that when arr[si] == data.
I AM GONNA SHARE THE CODE
Is this approach better
package recursion; public class LastIndex { public static int index = 0; public static void main(String[] args) { int[] arr = { 3, 8, 1, 8, 8, 7 , 8 }; int si = 0, data = 80; System.out.println(lastIndex(arr, si, data)); } public static int lastIndex(int[] arr, int si, int data) { if (si == arr.length) { return -1; // Base Case } if (arr[si] == data) { index = si; lastIndex(arr, si + 1, data); return index; } return lastIndex(arr, si + 1, data); } }
yaa this approach is also correct…but in this case you can make your function return type as void…dont both retusrn and static approaches
