The method given below is intended to find the number that is the minimum of all the numbers in
the Vector v that are larger than the minimum of the elements in v. You may assume that v contains
at least two elements, and that that the first two elements are different numbers.


i. Describe a vector of Integers that will give the correct result using the above method.

ii. Describe a vector of Integers that will give incorrect results using the above method.

oops, i've just spotted it, its the else if statement inside the for loop will not be executed if the the first if statement inside the for loop is not executed.. right?

If your minimum number is duplicated: i.e., {8, 9, 10, 8} the function will return 8 instead of 9. (The instructions only state that the first two elements are different; it says nothing about the uniqueness of these numbers)
(Edit begins here, after I saw your reply)
The else if has nothing to do with it, me thinks. It gives the same result
