Given an algorithm that determines if there is a pair of duplicate entries in the sequence. Input: a1, a2,...,an n, the length of the sequence. Output: "Yes" if there is a duplicate pair and "No" if the elements in the sequence are distinct. For i = 1 to n - 1 For j = i+1 to n If ( ai = aj ), Return("Yes") End-for End-for Return( "No" )

Which description corresponds to the type of input that will cause the inner loop of FindDuplicate to execute the most number of times?
