Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
There are a total of A + B cats and dogs. Among them, A are known to be cats, but the remaining B are not known to be either cats or dogs.
Determine if it is possible that there are exactly X cats among these A + B animals.
Constraints
* 1 \leq A \leq 100
* 1 \leq B \leq 100
* 1 \leq X \leq 200
* All values in input are integers.
Input
Input is given from Standard Input in the following format:
A B X
Output
If it is possible that there are exactly X cats, print `YES`; if it is impossible, print `NO`.
Examples
Input
3 5 4
Output
YES
Input
2 2 6
Output
NO
Input
5 3 2
Output
NO
Submitted Solution:
```
A,B,C=list(map(int,input().split(" ")))
if B>=X:
print("YES")
else:
print("NO")

Provide a correct Python 3 solution for this coding contest problem.
It is November 18 now in Japan. By the way, 11 and 18 are adjacent Lucas numbers.
You are given an integer N. Find the N-th Lucas number.
Here, the i-th Lucas number L_i is defined as follows:
* L_0=2
* L_1=1
* L_i=L_{i-1}+L_{i-2} (i≥2)
Constraints
* 1≤N≤86
* It is guaranteed that the answer is less than 10^{18}.
* N is an integer.
Input
Input is given from Standard Input in the following format:
N
Output
Print the N-th Lucas number.
