WebJun 8, 2024 · The tour starting at vertex $6$ and ending at $4$ we visit the vertices $[6, 2, 1, 3, 1, 4]$.Among those vertices the vertex $1$ has the lowest height, therefore $\text{LCA(6, 4) = 1}$.. To recap: to answer a query we just need to find the vertex with smallest height in the array $\text{euler}$ in the range from $\text{first}[v_1]$ to $\text{first}[v_2]$. ...
