As you begin to iterate through the set, change the array as a[k]=x and k++, where x represents an element in the set. We will print the elements present in the index range from i=0 to i=k-1 before returning the value of k, which is now the total number of unique elements in...

Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct. 求数组中是否有重复元素问题。
