Imagine a collection of nuts and bolts that are all together in one pile on a table. Describe, in pseudocode, how you would find all matching pairs of nuts and bolts. You need to find one solution for each of the problem-solving approaches given below. For each of your solutions, determine how many comparisons of pairs of nuts and bolts you might have to make in the best- and worst-case scenario. You can assume that there are complete pairs, no single nuts or bolts and that for each bolt, there is exactly one nut that fits.

I'm confused about how to apply the solution into pseudocode, please help.
