Last occurrence?

#1

how will we last from last using recursion ? in the last occurrence recursion

#2

Here’s the algorithm for that:-

Step 1: To solve this using recursion, make a recursion function with inputs, and a variable currIndex to traverse the input array.

Step2: Base Case:- If currIndex == size of the input array, return -1, i.e element not found.

Step3: Take input of next recursion call ,withcurrIndex incremented by 1 , in a variable ‘index’.

Step 4:
If(index == -1 && input[currIndex] == x)
Return currIndex
Else
Return index;
