Question

Choose the code snippet which uses recursion for linear search.

Options:

A . public void linSearch(int[] arr, int first, int last, int key){

B . public void linSearch(int[] arr, int first, int last, int key) {

C . public void linSearch(int[] arr, int first, int last, int key){

D . public void linSearch(int[] arr, int first, int last, int key){

Answer: Option A

Every time check the key with the array value at first index, if it is not equal then call the function again with an incremented first index.
