For problem statement at 0-999/100-199/100-109/101/problemC.txt this is a correct solution, but verifier at 0-999/100-199/100-109/101/verifierC.go ends with All tests passed can you fix the verifier? package main

import (
	"bufio"
	"fmt"
	"os"

	x, y int64
}

func rot(v Vec) Vec {
	return Vec{v.y, -v.x}
