panic: invalid argument to Intn

goroutine 1 [running]:
math/rand.(*Rand).Intn(0x8f3020?, 0xc000012018?)
        /usr/local/go/src/math/rand/rand.go:168 +0x65
main.run({0xc0000220a0, 0x5, 0x5})
        /drone/src/main.go:120 +0x4c5
main.main()
        /drone/src/main.go:22 +0x32

math.Rand panics when it is given an upper bound less than or equal to 0
