int l=nextInt();
  int r=nextInt();
  int k=nextInt();
  int x=r-l+1;
  if(l==r&&l==1){
    out.println("no");
    continue;
  }
  if(l==r&&l!=1){
    out.println("yes");
    continue;
  }
  if(x%2==0||l%2==0){
    x=x/2;
  }
  if(x%2==1&&l%2==1){
    x=(x/2)+1;
  }
  if(k>=x){
    out.println("yes");
  }
