One of your customers wants you to build a personal server that he can use in his home. One of his concerns is making sure he has at least one backup of their data stored on the server in the event that a disk fails. You have decided to back up his data using RAID. Since this server is for personal use only, the customer wants to keep costs down. Therefore, he would like to keep the number of drives to a minimum. Requried:
What RAID systems would BEST meet the customer's specifications?

The following code performs a familiar operation upon a specified subrange of an array of integers. void orderedinsert (int arr[], int first, int last, int target) // insert target into arr such that arr[first..last] is sorted, // given that arr[first..last-1] is already sorted. { int i = last; while ((i > first) & & (target < arr[i-1])) { arr[i] = arr[i-1]; i = i - 1; } arr[i] = target; } using the style of the standard library generic functions as a guide, rewrite this so that it can work on a subrange of arrays or linear sequence containers of any element type.
