Note: answer is not

(E,21) -> (A,10) (I,42)->(E,21) (I,42)->(N,30) (N,30)->(M,40) (N,30)->(X,41)

nor is it

(E,21) -> (A,10) (I,42)->(E,21) (I,42)->(M,40) (M,40)->(N,30) (N,30)->(X,41)

Imagine we have the following RST, where nodes are (key,priority) tuples: Gravizo I 42 E 21 M 40 A 10 N 30 Its edge list is the following: (E, 21) -> (A,10) (1,42) -> (E, 21) (1,42) -> (M, 40) (M, 40) -> (N,30) What would be the edge list of the RST resulting from inserting (X,41) ? Remember to submit your edges in increasing alphabetical order
