Q$3.$ Consider a network represented as $G,$ where the density of the network is denoted by $(G).$ Let's

define $(u,G)$ as the set of neighbors $($friends$)$ of a node $u$ in $G.$ Additionally, $(S)$ refers to the induced

subgraph on the set of nodes $S$ from $G,$ encompassing all nodes in $S$ along with their connections with

other nodes in $S.$ In this context, elaborate how can you express the clustering coefficient of a node $u$ in

terms of the network density $,$ and $.$
