Output

10 1 5

14


### Explanation:

�=10, which means that for the first hour, Chef has to pay Rs. 10.
�=1, which means that for every extra hour, Chef has to pay Rs. 1.
Chef needs to park for �=5 hours.

So, for the first hour, she will pay Rs. 10. And for the 5−1=4 hours extra, she will pay 4∗1=Rs. 4. So in total, she has to pay 10+4= Rs. 14.

### Sample 2:

991


### Explanation:

�=1, which means that for the first hour, Chef has to pay Rs. 1.
�=10, which means that for every extra hour, Chef has to pay Rs. 10.
Chef needs to park for �=100 hours.

So, for the first hour, she will pay Rs. 1. And for the 100−1=99 hours extra, she will pay 99∗10=Rs. 990. So in total, she has to pay 1+990= Rs. 991.

### Sample 3:

Input

Output

10


### Explanation:

�=10, which means that for the first hour, Chef has to pay Rs. 10.
�=15, which means that for every extra hour, Chef has to pay Rs. 15.
Chef needs to park for �=1 hours.

So, for the first hour, she will pay Rs. 10. And she does not have to pay any more. So in total, she has to pay Rs. 10.
