KNN$.$ Consider the following one$-$dimensional dataset. Each example is described by one numerical feature $x$ and has a

discrete label yin$\{-,+\}.$

Consider xin$[0,12].$ What is the output of a $1-$NN $($nearest neighbor classifier$)?$ Provide ALL the intervals in $[0,12]$

labeled $1.$ For example, $6,7$ is labeled $1.$ In case of ties, choose the point on the left. Show all your steps.
