Assume that you start with an array of numbers as follows:

$348,256,543,321,44,909,365,47$

Match the intermediate result on the left with the correct sorting algorithm on the right.

Hint: You can either $1)$ apply each of the listed sorting algorithms on the right and then look through each of the intermediate results or $2)$ look at the intermediate results and think each algorithm could have produced it$.$
