Find the Duplicate Number Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Note: You must not modify the array (as...
Count of duplicate elements:3Duplicate elements in the array:[1,3,5]Unique elements in the array:[2,4] 2. UsingStreamandSet Java Setclass stores only the distinct elements. We can use this feature to find the distinct elements in the array and then find unique and duplicate elements usin...
