Given a vector of real numbers x, find the index idx of n th maximum value. If nth maximum occurs more than once, return the indices of all those occurences.
Example 1:
Input: x = [2 4.5 3 1 3.33], n = 4
Output: idx = 1, since 4th maximum is 2
Example 2: Input: x = [2 4.5 3.33 3 1 3.33], n = 2
Output: idx = [3 6], since 2nd maximum is 3.33
Apologies.Test case 8 is corrected now.
in test 8 I believe it should read either "n=3" or "y_correct=2" (the second highest value is 4.5, not pi)...
I agree...
