8. Give an example of a problem other than computing the greatest common
divisor for which you know more than one algorithm. Which of them is
simpler? Which is more efficient?
9. Consider the following algorithm for finding the distance between the two
closest elements in an array of numbers.
ALGORITHM MinDistance (A[0..n-1])
Input: Array A[0..n - 1] of numbers
//Output: Minimum distance between two of its elements
dmin <o
for i 0 to n - 1 do
-0
for j←0 to n - 1 do
return dmin
AL
if i ‡ j and \A[i] – A[j] <dmin
dmin A[i]- A[j]|
Make as many improvements as you can in this algorithmic solution to the
problem. If you need to, you may change the algorithm altogether; if not,
improve the implementation given.
