Learning SQL solution codechef

Chef has recently started learning from the new CodeChef SQL course.

He has a table which initially has $R$ rows and $C$ columns. He then adds $E$ extra rows to it. How many total cells does he have finally?

Input Format

The only line in the input contains three space-separated integers $R$, $C$, and $E$ — the number of initial rows, the number of columns, and the number of extra rows added, respectively.

Output Format

Output on a new line, a single integer, which should be the final total number of cells in the table.

5 2 1

12

Explanation:

There are initially $5$ rows, and $2$ columns. So the initial number of cells was $5\ast 2=10$. Then, $1$ extra row was added. So now the table has $6$ rows, and $2$ columns. So the total number of cells is now $6\ast 2=12$, which is the answer.

Sample 2:

6 10 3

90

Explanation:

There are initially $6$ rows, and $10$ columns. So the initial number of cells was $6\ast 10=60$. Then, $3$ extra rows were added. So now the table has $9$ rows, and $10$ columns. So the total number of cells is now $9\ast 10=90$, which is the answer.

Sample 3:

1 1 1 

2

Explanation:

There are initially $1$ rows, and $1$ columns. So the initial number of cells was $1\ast 1=1$. Then, $1$ extra row was added. So now the table has $2$ rows, and $1$ columns. So the total number of cells is now $2\ast 1=2$, which is the answer.

Sample 4:

100 100 100

20000

Explanation:

There are initially $100$ rows, and $100$ columns. So the initial number of cells was $100\ast 100=10000$. Then, $100$ extra rows were added. So now the table has $200$ rows, and $100$ columns. So the total number of cells is now $200\ast 100=20000$, which is the answer.
