Input: Two sorted linked list List a, List b. Since HashSet does not allow duplicates. Then we simply sort the concatenated list. One solution to do so you need to use two loops (nested) where the inner loop starts with i+1 (where i is the variable of the outer loop) to avoid repetitions. These queries retrieve two different sets of records; one from the Product Orders table and one from the Product Purchases table. Sorting a list according to natural ordering of elements Basically, a list can be sorted if only all of its elements are mutually comparable by implementing the Comparable interface. If the result of the remapping function is null, it removes the result. Then, it combines two individual result sets into one and eliminates duplicate rows. We can use a method like ToList () to go from an IEnumerable to a List again. If items itself declares a complex type ("type" : "object") then the generic type of the List or Set will itself be a generated type e. As there is no predefined functions in ArraysList to remove duplicates, we can convert the arraylist to set and convert back then to arrayslist. Two time All State player & All American in 1982.
