Implement the function compute$($startNodeId$,$ fromIds, tolds$)$ which should

retum the last node id of the network found when starting from the node with id startNodeId and following the links of the network.

In the above example, the endpoint node when starting from node #$2($or any other

node$)$ is node #$5.$

fromIds and tolds are two arrays of the same length which describe the one$-$way

links of the network $($fromIds $[$i$]$ is linked to tolds $(11).$

In the example above, fromIds is:

$11,7,3,4,2,6,9]$

and tolds is:

$[3,3,4,6,6,9,5]$

In case you run into a loop when traversing the network, the function should retum the id of the last node traversed before closing the loop.
