# Hackerrank - Fibonacci Modified Solution

We define a *modified* Fibonacci sequence using the following definition:

Given terms and where , term is computed using the following relation:

For example, if and ,

- ,
- ,
- ,
- and so on.

Given three integers, , , and , compute and print the term of a *modified Fibonacci sequence*.

**Function Description**

Complete the *fibonacciModified* function in the editor below. It must return the number in the sequence.

fibonacciModified has the following parameter(s):

*t1*: an integer*t2*: an integer*n*: an integer

**Note:** The value of may far exceed the range of a -bit integer. Many submission languages have libraries that can handle such large results but, for those that don't (e.g., C++), you will need to compensate for the size of the result.

**Input Format**

A single line of three space-separated integers describing the respective values of , , and .

**Constraints**

- may far exceed the range of a -bit integer.

**Output Format**

Print a single integer denoting the value of term in the modified Fibonacci sequence where the first two terms are and .

**Sample Input**

```
0 1 5
```

**Sample Output**

```
5
```

**Explanation**

The first two terms of the sequence are and , which gives us a modified Fibonacci sequence of . Because , we return the term.

### Solution in Python

```
def fib(a,b,n):
for i in range(n-1):
a,b = b,a+b**2
return a
a,b,n = map(int,input().split())
print(fib(a,b,n))
```
