Question

3. You are given k sorted arrays A1... Ak of keys. That is, each A is an array that might contain keys A[1..ni] Each key is a float number. The total number of keys in all arrays is n. Your goal it to sort all these keys in time O(n log k) (a) Suggest a solution under the assumption that there are no constrains on memory memory cell takes a availability nor on access time constant time. to memory, and access to each (b) Suggest a solution under the following assumptions: Each 'Write' Operation is much slower than a 'read' operation (as is commonly the case for Solid State Driver) However, you have access to fast memory containing O(k) words elaborate, assume that your computer's memory contains two major components i. SlowMem - a slower memory. Reading and writing from this components are slower. The input arrays are stored in SlowMem, and the final output should be writing to SlowMem. Your algorithm should keep the number of reads/writes from SlowMem to the bare minimum ii. FastMem - a faster memory unit. Could only contain, say, 10k words.
