How many integers not less than $A$ and not more than $B$ are there? ## Constraints * $1 \leq A \leq 100$ * $1 \leq B \leq 100$ * $A$ and $B$ are integers. ## Input Input is given from Standard Input in the following format: $A$ $B$ [samples]

Samples

Input #1

2 4

Output #1

3

We have three integers not less than $2$ and not more than $4$: $2$, $3$, $4$, so we should print $3$.

Input #2

10 100

Output #2

Input #3

3 2

Output #3

0

We have no integers not less than $3$ and not more than $2$, so we should print $0$.
