Compressing Array\ less than or equalition\ The goal is to reduce\ Exampl\ 3 Let array

a=[2,3,3,7,3,5]

and

k=20

\ 4\ This is the list of operations that will give us the Smallest array (1-based indexing):\ Merge the elements at indices

(1,2)

, resulting array will be

-[6,3,7,3,5]

\ Merge the elements at indices

(1,2)

, resulting array will be -

18,7,3,5

\ 6\ 5\ Merge the elements at indices

(3,4)

resulting array will be -

18,7,15
