#### Example 1: last index of a number using recursion.** int lastIndex (int input [], int size, int x) { if (size == 0) { return -1; } int answer = lastIndex (input + 1, size - 1, x); if (answer** != **-1) { return answer +** 1; } if** (input** [0] ==** x)** {** return** 0; } else** { return** -1;. **Reversing an array using Recursion** is an example of Tail **Recursion** . We maintain two in-variants “i” and “j”. “i” holds starting element **index** and “j” holds ending element **index** of the array. As long as “i” is less than “j”, we swap two elements starting and ending element of the array. Increment “i” and decrement. **Using recursion** to get sum **of numbers** 9 ; Java integer array reverse **recursion** problem 5 ; array of void and other problems 7 ; How to determine the sum of the squares of two **numbers using** a **recursive** method? 9 ; Java **Recursion** Help 8 ; main(int argc, char *argv[]) 20 ; Need **Recursion** and File I/O Java Help! 3 ; **Recursion** 2 ; c++ arrays, help.

**Recursion**occurs when any function calls itself. One of the big differences between

**recursion**and looping is the way that a

**recursive**function terminates. In the above example, a for loop ends at the end of the sequence it is looping over. However, a

**recursive**function could continue indefinitely since it doesn’t necessarily have a sequence. The function must be recursive and the list provided as a parameter may not be modified. Example: >>>lastIndex ( [1,2,3,4,5,1],1) 5 >>>lastIndex ( [1,4,7,2,3,2],3) 4. My current code: def

**lastIndex**(lst,n): if lst [0] ==n:

**return**-1 else: 1 +
