const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void async function () {
    // Write your code here
    let tokens = await readline()
    tokens = tokens.split(' ').map(a=>parseInt(a))
     
    //console.log(tokens[0]-1)
    if(tokens[0]-1>=tokens[1]){
        console.log("YES")
    }else{
        console.log("NO")
    }
    
}()

最大困难是思考题目说的什么意思
