WebApr 22, 2024 · However, for id 3, the v with smallest absolute value is v2 = -2, yet you show x = +2. I can't make sense of that. There is another issue. Suppose we had v1 = 1, v2 = -1, v3 = 5. Then v1 and v2 both have the smallest absolute value, namely 1. But it is unclear whether x should be 1 or -1, and how that would be decided.
