$\backslash$table$[[$Ex$3.,$Similar$],[$Nodes$,],[$points$),]]$

Write a function called SimilarNodes$($self$,$ tree$2),$ which returns true if the current tree and tree $2$ have similar nodes values regardless of their structure. For example, the current tree may have values in BFT $(4,2,6,1,3,5,7)$ while tree$2$ may have values in BFT $(5,3,7,2,4,6,1),$ where both trees have values from $1-7,$ which should return true using this function.
