For each example choose one of the following sorting algorithms and carefully justify your choice: heapsort, radixsort, countingsort. give the expected runtime for your choice as precisely as possible. if you choose radix sort then give a concrete choice for the basis (i. e. the value of "r" in the book) and justify it. sort the length 2^16 array a of 128-bit integers on a device with 100mb of ram. sort the length 2^24 array a of 256-bit integers on a device with 600mb of ram. sort the length 2^16 array a of 16-bit integers on a device with 1gb of ram.
