1. Among Selection Sort, InsertionSort, MergeSort, QuickSort, and HeapSort, which algorithm would you use for each list-sorting situation below? Justify your answers. A question might have multiple right answers, but each definitely has at least one wrong answer. (a) The list has several hundred records. The records are quite long, but the keys are very short. (b) The list has about 45,000 records. It is necessary that the sort be completed reasonably quickly in all cases. There is barely enough memory to hold the 45,000 records. (c) The list has about 45,000 records, but it starts off only slightly out of order. (a) The list has about 25,000 records. It is desirable to complete the sort as quickly as possible on the average, but it is not critical that the sort be completed quickly in every single case
