Question $9$

id:

size:

Above are the id and size arrays for an instance of the book's

WeightedQuickUnionUF class $($the weighted quick union solution to the Union$-$Find

problem$).$

What will the size array look like after a call to union$(1,7)?$

Write down the numbers in order as they appear in the array using a comma

separated list. For example, if you believe the size array is unchanged, your answer

would be

$1,1,4,2,1,2,2,1$
