### Problem Statement

How many triples of non-negative integers $(a, b, c)$ satisfy $a+b+c \leq S$ and $a \times b \times c \leq T$?

### Constraints

• $0 \leq S \leq 100$
• $0 \leq T \leq 10000$
• $S$ and $T$ are integers.

### Input

Input is given from Standard Input in the following format:

$S$ $T$


### Output

Print the number of triples of non-negative integers $(a,b,c)$ satisfying the conditions.
