fn main() {
    let mut buf: String = String::new();

    let mut iter = buf.split_whitespace();
    let k: usize = iter.next().unwrap().parse().unwrap();
    let s: usize = iter.next().unwrap().parse().unwrap();

    let mut pattern = 0;
    for z in 0..(k+1) {
        for x in 0..(s+1) {
            let f = s as i16;
            let g = (z + x) as i16;
            if f-g >= 0 {
                pattern += 1;
            }
