Web我们知道如果u,v之间没有边，那么w[u][v]=INF，如果我们的INF取0x7fffffff，那么d[u]+w[u][v]会溢出而变成负数，更一般的说，0x7fffffff不能满足“无穷大加一个有穷的数依然是无穷大”，它变成了一个很小的负数。 比较精巧的一个INF无穷大值是0x3f3f3f3f。 Web6 sep. 2024 · inf = 0x3f3f3f3f inf = 0x3f3f3f3f在一般场合作为无穷大来使用，int类型真正的无穷大是 inf = 0x7fffffff（32_bit的最大值），它能够表示int的无穷大，但是当在它的基础上加上某个数的时候会变成负数。 准确的说：inf = 0x7fffffff不满足“无穷大加上一个无穷大仍然是无穷大” 所以我们引入 inf = 0x3f3f3f3f，它的 ...
