Answer:
Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as "low-level formatting".[1] Partitioning is the common term for the second part of the process, making the data storage device visible to an operating system.[1] The third part of the process, usually termed "high-level formatting" most often refers to the process of generating a new file system.[1] In some operating systems all or parts of these three processes can be combined or repeated at different levels[3] and the term "format" is understood to mean an operation in which a new disk medium is fully prepared to store files. Some formatting utilities allow distinguishing between a quick format, which does not erase all existing data and a long option that does erase all existing data.
As a general rule,[nb 1] formatting a disk by default leaves most if not all existing data on the disk medium; some or most of which might be recoverable with privileged[nb 2] or special tools.[4] Special tools can remove user data by a single overwrite of all files and free space.[5]

Answer:
def max_n(arr, n):
arr.sort()
i = len(arr)-n
return arr[i:]
Explanation:
Define a function called max_n that takes two parameters, an array and an integer
Sort the array
In order to get the last n largest values, we need to slice the array. To do that we need a starting point. Our starting point of slicing will be the "lentgh of the array - n". That means, if we start slicing from that index to the last in the sorted array, we will get the last n largest values.
Assume array is 10, 2, 444, 91 initially.
When we sort it, it becomes 2, 10, 91, 444
Now let's say we want last 2 largest values, our sliced array index should start from 2 and go until the end
i = 4 - 2 = 2 → arr[2:] will return us 91 and 444

Answer:
1.25 per unit
Explanation:
Number of units to sell = 100,000
Price per unit = 2
Fixed expense = 75000
At break even point :
Revenue = total expenses
Total expenses = fixed cost + variable cost
Let variable cost = x
Revenue = units to sell * price per unit
Revenue = 100,000 * 2 = 200,000
Hence,
Fixed cost + variable cost = Revenue
75000 + x = 200,000
x = 200, 000 - 75000
x = 125,000
Variable cost = 125,000
The variable expense per unit is thus :
Variable expense / number of units
125,000 / 100,000 = 1.25 per unit
