$3.(20$ points$)$ Let $\backslash ($ G$=($V$,$ E$)\backslash )$ be an undirected connected graph with $\backslash ($ n $\backslash )$ vertices and $\backslash ($ m $\backslash )$ edges. Each edge in $\backslash ($ G $\backslash )$ is also given an non$-$negative integer weight. Given a path $\backslash ($ P $\backslash )$ in $\backslash ($ G $\backslash )$ from a vertex $\backslash ($ u $\backslash )$ to a vertex $\backslash ($ v $\backslash ),$ the bottleneck weight of $\backslash ($ P $\backslash ),$ denoted by $\backslash ($ w t$($P$)\backslash ),$ is the minimum edge weight in $\backslash ($ P $\backslash ).$ A maximum bottleneck path between $\backslash ($ u $\backslash )$ and $\backslash ($ v $\backslash )$ is the path $\backslash ($ Q $\backslash )$ between $\backslash ($ u $\backslash )$ and $\backslash ($ v $\backslash )$ such that $\backslash ($ w t$($Q$)\backslash$geq w t$($P$)\backslash )$ for all paths between $\backslash ($ u $\backslash )$ and $\backslash ($ v $\backslash ).$ Our problem is to report the maximum bottleneck paths between all pairs of vertices in $\backslash ($ G $\backslash ).$ Show that this problem can be solved by finding the minimum spanning tree of some graph. Explain the running time of your algorithm.
