Write a method called switchPairs that switches the order of values in the list in a pairwise fashion. Your method should switch the order of the first two values, then switch the order of the next two, switch the order of the next two, and so on. If the list contains an odd number of values, the final element is not moved. For example, if the list initially stores [10, 25, 31, 47, 52, 68, 77], your method should switch the first pair (10 and 25), the second pair (31 and 47), and the third pair (52 and 68) to yield [25, 10, 47, 31, 68, 52, 77].

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
