Which key element will be best for merge sort and why?
There is no key element in a merge sort. Unlike quick sort which requires a key element (a pivot) to recursively divide a subset into two subsets, merge sort simply divides a subset into subsets of 1 element and merges adjacent subsets together to produce sorted subsets. When there is only one subset remaining, the subset is fully sorted.
How many subsets does set A have if the set A has 3 elements?
In a subset each element of the original may or may not appear - a choice of 2 for each element; thus for 3 elements there are 2 × 2 × 2 = 2³ = 8 possible subsets.

How do you list 3 element subsets of a 7 element set?
If your 7 element set is {a, b, c, d, e, f, g}, you would list a 3 element subset by taking any 3 elements of the set eg., {a, d, g} or {b, c, f}, etc. To count all of the subsets, the formula is 7C3, where 7C3 is 7!/(3!*4!), or 35 different unique 3 element subsets of a 7 element set.
What are the subsets of number 8?
The number 8 is not a set and so cannot have any subsets. The set consisting of the number 8 is a set and, since it has only one element in it, it has two subsets: itself and the null set.
