Dave has a balance with which to weigh objects, and a number of reference weights of known value. All weights are integers between 1 and 100000000 (10^8), inclusive. The balance has 2 pans, each of which can hold any number of objects. The balance will indicate which pan contains more total weight, or that the pans contain equal amounts of weight.
Dave has a problem. His arch nemesis, Earl, has removed the labels from some of the weights, in an attempt to prevent Dave from knowing their values. Dave will attempt to recover the values of the unlabeled weights using the balance and the remaining weights. You are asked to figure out if Dave will succeed.
You will be given a int labeled giving the values of all of the weights with their labels intact, and int unlabeled, the actual values of the unlabeled weights. Return a String with the same number of elements as unlabeled, each "yes" if Dave can determine the value of the corresponding unlabeled weight, or "no" otherwise (quotes for clarity only).
