@[Kinandra](/user/51237) 用小的拍?

@[hsl2363](/user/51005) 用标程
by Kinandra @ 2020-01-08 18:31:52
@[Kinandra](/user/51237) 要不试一下造点小的数据,n只有5-10那种,m可以开很大

@[hsl2363](/user/51005) 试过了，没用，已弃

话说为什么把`fa[ch[t][0] = build(l, p - 1)] = fa[ch[t][1] = build(p + 1, r)] = t;`改成`ch[t][0] = build(l, p - 1) ,ch[t][1] = build(p + 1, r),fa[ch[t][0]]=fa[ch[t][1]] = t;`就对了啊
是奇怪的ub吗
本人也遇到了同样的问题
